The ongoing COVID-19 pandemic and corresponding traffic growth has apparently taken its toll on network capacity at Mediacom, forcing the company to reach out to a growing number of its heavy uploaders and telling them to reduce usage or face a speed throttle or the possible closure of their account.

An East Moline, Ill. Mediacom broadband customer of 10 years was offended to receive a phone call from Mediacom’s “Fraud and Abuse Department” telling him he was overusing his gigabit internet account, which includes a 6 TB data cap. The customer was certain he never exceeded Mediacom’s data cap, and in fact recorded 2.5 TB of usage over the last month, well below his data allowance.

Mediacom’s representative explained the problem was not with how much he downloaded.

“He told me my upload was 450 GB over their average and if I didn’t reduce my usage they would either throttle or disconnect me,” DSL Reports‘ reader poonjahb wrote. “I argued that I used less than half of the total data allowed by my plan, but he said my 1.2 TB of upload was too much and that this was my warning.”

Other Mediacom customers across the Midwest also received similar letters in early January, and several contacted Stop the Cap! Many were already annoyed Mediacom had earlier imposed a data cap, but were incensed they were now being threatened when usage was well under that cap.

“I am paying for gigabit internet service just to never have to worry about a data cap,” said Cory, a Mediacom customer in Missouri. “It comes with a 6,000 GB monthly allowance, which is way more than I will ever use, but I still received a warning letter claiming I was uploading too much. I discovered I used about 900 GB over the last two months, setting up a cloud backup of my computer. At most I can send files at around 50 Mbps, which they claim is interfering with other customers in my neighborhood. I don’t understand.”

Several filed complaints with the FCC, which the agency forwarded on to Mediacom customer service. Most received form letter replies.

COVID-19 Pandemic Causes Traffic Surge, Mediacom Tells Stop the Cap!

“Mediacom routinely reviews both download and upload usage trends to determine if any customers are using a disproportionate share of bandwidth compared to average users,” explains Thomas J. Larsen, senior vice president of government and public relations at Mediacom. “If a customer falls into the top 0.5% of downstream or upstream capacity users in a given month, they may receive a letter or call from Mediacom regarding their usage. This would apply to both business and residential customers. The reason for contacting the customers is to explain that their usage patterns may be degrading the performance of the network and affecting other users.”

Larsen pointed to statistics from the cable industry’s largest trade group, NCTA – The Internet & Television Association, which reported a 31.8% total cumulative growth in downstream internet traffic and a 51.1% increase in upstream traffic since the spring COVID-19 lockdowns back in March 2020.

A Mediacom letter sent to customers complaining to the FCC about the practice cited network “stress” caused by excess upstream traffic. Larsen told Stop the Cap! the company regularly reviews customers’ download and upload traffic trends, looking for outliers that use a disproportionate share of bandwidth compared to average users. Larsen would not admit if heavy users were noticeably affecting other customers with congestion-related slowdowns, but said the company was “reaching out … more frequently than before” to the top 0.5% of traffic generating users anyway. He also noted this policy equally applied to both residential and business accounts.

“This is not the easiest topic to explain because internet usage is growing rapidly in this work from home/study from home environment, so it is difficult to give an exact number that puts a customer into the 0.5% category because that number changes from month to month,” Larsen noted. “Understandably, that may make the policy seem arbitrary when we are really just trying to stay in line with moving usage trends.”

Internet Service Providers Have Wide Latitude to Cut Off Heavy Users

Virtually every internet service provider has a provision in their acceptable use policy allowing them to terminate or restrict service when a customer causes problems for that provider. Mediacom is no exception, telling subscribers “without limitation, customer’s usage of the service cannot restrict, inhibit, interfere with or otherwise disrupt or cause disruption, performance degradation of other users or impair or threaten to impair the operation of Mediacom’s systems or network.” This policy is in addition to whatever data usage plans are in place.

But Larsen insists Mediacom is not trying to alienate its customers.

“[We want to] work with our customers to address this issue in a productive manner,” Larsen told Stop the Cap!

At the moment, the only solution seems to be to reduce usage enough to stay off of the company’s “top 0.5%” radar.

Mediacom’s Warning Letters Uncommon Among Other Providers

Mediacom’s crackdown on heavy usage has not been copied by most other U.S. providers. Although traffic growth has been measured by virtually every provider in the country, most providers are mitigating possible service degradation by aggressively upgrading capacity or quietly node splitting neighborhoods experiencing the highest traffic growth, which immediately eases congestion issues.

The company did not indicate if its usage crackdown was temporary or if any planned network upgrades would allow it to ease restrictions sometime in the near future.

Other small providers dealing with congestion issues found a better solution sending letters to high traffic customers explaining forthcoming upgrades and temporarily requesting they limit upstream traffic during peak usage times, while not penalizing them for any off-peak traffic. That might prove to be a useful compromise between Mediacom and its customers and preserve goodwill.

Nathan Gray woke up one morning this month and received an alarming notification from Comcast, his internet provider, claiming he had exceeded his Comcast terabyte data cap and was being billed an additional $10 for a 50 GB allotment of extra data.

“This has never happened before and I was only six days into my monthly billing cycle, so I assumed it must be a mistake,” Gray told Stop the Cap! “But Comcast told me it wasn’t a mistake.”

Gray was hardly alone. One month earlier, “Bogreenwoo” discovered his family had blown the roof off their internet usage, exceeding 1 TB by the middle of the billing cycle, with more usage piling up hour after hour.

“Xfinity was adding 50 GB blocks every day at $10 each and calls to tech support were no help,” he shared on Comcast’s customer support forum.

Similar complaints are brought up on that forum at least weekly, if not more often. Comcast counterclaims that usage exceeding 1 TB a month is so rare, it represents only about 1% of its customer base. But customers with huge internet bills from Comcast who stumble their way to the company’s support forum strongly dispute that notion.

“Well good luck with finding a solution or even finding anyone at Comcast who cares or anyone anywhere else as far as that goes,” shared “Amaasing.” “I have had this issue more than once and have talked with every vice president of customer service and had discussions with the security department and even filed a complaint with the FCC and nothing happened at all.”

Some users, like Amaasing, have received so many bills stung with overlimit fees they now turn their computers off in the evening and unplug their cable modems. In many cases the usage keeps rising anyway.

“Today when I logged in, I had apparently used 196 GB yesterday,” Amaasing wrote. “196 GB in 24 hours?  Seriously?”

For most customers in this predicament, Comcast is quick to blame customers for the usage and leave the detective work up to them. Customer support will not entertain suggestions their usage meter is inaccurate. In their view, it is more likely someone is illicitly connected to your Wi-Fi and stealing your service or you are running some bandwidth-heavy application or your computer has been hijacked by hackers or pirates.

While you are left to investigate which of these might be true, Comcast is free to continue billing your account overlimit fees.

Comcast claims it will forgive customers who exceed their data allowance twice ‘a year’:

“We’ll provide you with two courtesy months, so you will not be billed the first two times you exceed a terabyte while you are getting used to the new data usage plan. This means that you will only be subject to overage charges if you use more than a terabyte for a third time in a 12-month period. If you use more than a terabyte two times or less in a 12-month period, your courtesy month balance will reset to two at the end of these 12 months. However, if you use more than a terabyte three times in a 12-month period, no more courtesy months will be given.”

After “courtesy months” expire, you are on the hook for whatever excess usage Comcast determines you have consumed. Some Comcast customers assume the courtesy month counter resets each calendar year, but in fact it only resets after 12 consecutive months of staying within your allowance limit.

What causes “excess usage” is anyone’s guess. Comcast customers have documented several recent causes why they have mysteriously started blowing through their 1 TB data allowance:

1. The growing prevalence of 4K video, the highest streaming video quality available through online video streaming services can be responsible for a sudden spike of usage. Netflix and other services that support 4K video content with high dynamic range can eat up 7 GB to 10 GB of data per hour. Many services allow you to downgrade your video settings with minimal quality loss. We recommend trying settings typically labeled 720 or 1080 — the lower the better if you are running up against your allowance.
2. Third party backup and cloud storage tools: That online backup or cloud storage service you are using may be malfunctioning. There are several reports about Amazon Drive having problems recently, causing files to be repeatedly transferred and driving up usage to several hundred gigabytes a day in some cases. If you use Amazon Drive and have seen a huge spike in usage, try uninstalling or turning off the service for several days and see if usage falls dramatically. Other file and computer backup services that store your data in the cloud can consume a lot of data, especially when installing them on a new computer for the first time. Even some cell phone backup services designed to store your photos in the cloud can malfunction and repeatedly try to send the same photos over and over. Disable these tools for several days and check your usage levels.
3. Third party usage: Family members doing something bandwidth intensive can also be responsible for dramatic usage spikes. Although downloading video game updates can consume very large amounts of data, game play itself typically has little impact on your data usage. Check with family members to see if they are watching high bandwidth video or have installed a file backup service. Less common is an uninvited guest on your Wi-Fi network. Comcast often points to Wi-Fi security as a major problem when a neighbor gains access to your internet connection to download huge numbers of files. You can change your Wi-Fi password to help lock down your network. Make sure not to use plain word passwords — use a mixture of letters, numbers, and symbols.
4. Comcast’s meter is simply inaccurate. There is no independent third-party verification or government oversight of Comcast’s usage meter. Most ISPs hire a third-party contractor to design and implement their data measurement meters, but those contractors are ultimately answerable to the provider — not to you, giving little peace of mind to consumers who are forced to trust their cable company to be honest. Our country’s Founding Fathers placed great importance on accurate measuring and weighing tools, so much so it is addressed in Section VIII of Article I of the U.S. Constitution. That section gives authority to Congress to establish accurate and regulated measurement tools. Each state has their own way of managing this, often with a bureau of weights and measurements that independently verifies and certifies — with a tamper-evident sticker, the accuracy of the food scale at your local grocer or the gas pump at a nearby service station. Comcast has resisted similar third-party oversight for its usage meter. But considering the company’s overlimit fees can add a substantial sum to customer bills, having this kind of oversight seems appropriate.

Avoiding the usage cap: Comcast ironically provides its own insurance plan to protect customers from its own arbitrary data allowance. For peace of mind, Comcast collects an extra $50 a month ($20 for gigabit speed DOCSIS 3.1 plans) if you wish to waive the data cap altogether. Data caps are completely under the control of Comcast and are especially prevalent in regions of the country where a lack of competition exists. But Comcast’s arguments in favor of data caps don’t wash at the nation’s second largest cable company – Charter Communications, which markets its internet service as having no data caps at all. In fact, Charter CEO Thomas Rutledge never saw much use for data caps at Charter or Cablevision, the company he used to head.

After four years of a gradually expanding “beta test” no customer wanted to be part of, Comcast’s never-ending data cap trial has increased data allowances for the first time since 2012.

Comcast customers in data cap trial areas tell Stop the Cap! their Comcast usage meter now reflects the new 1,024GB allowance Comcast promised back in April (some customers in Atlanta seem to have gotten a 2,048GB allowance for an unknown reason). It’s a major improvement over the old 300GB cap many customers endured with expensive overlimit fees that applied when they exceeded their allowance. Comcast will continue to bill those overlimit fees of $10 for each 50GB increment of excess usage over the allowance, but now plans to cap those overlimit fees at $200 a month.

“The new meter showed up June 1st in southern Florida, and it’s about time,” said our reader Javier from Miami. “But wouldn’t you know, Comcast screwed us out of one more month of paying their $30 extortion fee to keep unlimited.”

300GB was not enough for many Comcast customers.

Javier is referring to Comcast’s unlimited usage insurance plan. For $30-35 extra, the cable company removes your data cap and you face no overlimit fees. But since Comcast bills one month ahead, a customer enrolled in the insurance plan paid for an unlimited June on their May bill. Now that usage allowances have more than tripled, Javier wanted to cancel his insurance for this month because he doesn’t come close to Comcast’s new cap.

No dice, replied Comcast, who canceled his unlimited insurance plan effective July 1.

“Once you begin a new month, you cannot stop the charges until the following month,” Javier explained, even though he canceled the plan on the 1st of the month. “They told me it was too late.”

Javier is still glad he canceled the insurance.

“If I didn’t, they planned to auto-enroll me in their new unlimited option, which costs a ridiculous $50 a month,” said Javier.

Not all Comcast service areas are subject to data caps. Comcast issued broad clarifications about the usage cap trial changes on its website:

New Data Usage Trials

On June 1, 2016, we will be migrating all customers currently in usage trials to a new 1 Terabyte plan, and the following is an overview. For more details on this trial plan, see Questions & Answers About Our Data Usage Plan Trials. For a detailed list of trial locations, see Is my area part of the data usage plan trials? For trial start dates, see Where will these plans be launched?

In the markets of Huntsville, Mobile and Tuscaloosa, Alabama; Tucson, Arizona; Little Rock, Arkansas;Fort Lauderdale, the Keys, and Miami, Florida; Atlanta, Augusta and Savannah, Georgia; Central Kentucky; Houma, LaPlace, and Shreveport, Louisiana; Maine; Jackson and Tupelo, Mississippi;Chattanooga, Greeneville, Johnson City/Gray, Knoxville, Memphis and Nashville, Tennessee;Charleston, South Carolina; and Galax, Virginia, we will increase our monthly data usage plan for all XFINITY Internet tiers to 1 terabyte (1,024 GB) per month and will offer additional gigabytes in increments/blocks ($10 per 50 GB, up to $200 each month). You will also be able to choose to enroll in an Unlimited Data Option for an additional recurring flat fee of $50 per month. Under this option, the 1 Terabyte data usage plan will not be enforced on your account. For more information on the Unlimited Data Option, see What is the Unlimited Data Option?

If you are an XFINITY Internet Economy Plus or Performance Starter customer, you can instead choose to enroll in the Flexible Data Option to receive a $5 credit on your monthly bill if you reduce your data usage plan to 5 GB. If you choose this option and use 6 GB of data or more in any given month, you will not receive the $5 credit and will be charged an additional $1 for each gigabyte of data used over the 5 GB included in the Flexible Data Option.
