A significant number of Comcast customers were without broadband, phone, and internet service for several hours Tuesday morning because of what the company called a “hardware issue.”

“Early yesterday morning, our engineers detected a hardware issue that impacted voice, video and Internet services for a subset of customers across the country for several hours,” Comcast said, in a statement. “During this time, customers also may have had difficulty reaching us by phone. Our engineers quickly identified and resolved the issue, and services have returned to normal. We appreciate our customers’ patience as we worked to fix this and are sorry that we inconvenienced them.”

Major parts of Boston, San Francisco, Seattle, and Portland were without service until 10:30am ET.

“Last night, Internet service for a number of our customers in the western part of the country was degraded or unavailable for several hours,” Comcast wrote on its blog this morning. “We had a team on this immediately, and were able to restore full service to most customers by 9pm PT.”

The cause of the failure – a defective piece of hardware – began that morning, which meant it took almost nine hours for Comcast to find the equipment responsible for eventually wiping out Internet service for millions of broadband customers up and down the west coast.

Most backbone networks, including Comcast’s, are designed to heal themselves and route traffic along alternate paths much like a detour would route automobile traffic around a street closed for construction.

One type of traffic that gets automatically rerouted is Domain Name System (DNS) traffic.  Unfortunately, some of that traffic shifted in an unexpected way and overloaded local DNS server capacity causing many customers to experience service interruptions.

The worst of the outage affected most California, Oregon, and Washington customers between 6:30-9:30pm PT, but many reported poor service for at least six hours before that.

“Our condolences on the death of your Internet,” wrote Upgrade Seattle, an advocacy group trying to convince the city to run its own public gigabit Internet service to compete with Comcast. “This is why we need a strong, accountable municipal Internet service throughout Seattle.”

Comcast has offered to placate angry customers with a $5 service credit for the outage, but offered conflicting information about how customers will get it.

Comcast spokeswoman Jennifer Khoury claimed the company will “proactively send the credit to affected customers.”

“Down Detector” shows the extent of Comcast’s latest service outage, which largely covers its entire service area in the states of Washington, Oregon, and the Bay Area region of California.

But other Comcast representatives, and the company’s own blog post, suggest otherwise.

Comcast’s policy states customer outage credits are not automatic, and callers to Comcast report customers must still ask for an outage credit to receive one.

“Comcast does not issue blanket service credits for outages,” reflects the policy of Comcast’s west coast divisions. The reason for that policy, according to Comcast spokesman Steve Kipp, is that Comcast prefers to work one-on-one with customers.

“You may have had somebody that may not have been home and did not even notice there was an outage,” Kipp offered. “Another customer may have lost valuable work time.”

But some people might be getting credits, if they got through to Comcast to complain about the outage as it happened.

“We are directly reaching out to those who reported problems last night to offer our apologies and a credit for lost service,” Comcast wrote on its blog this morning.

For everyone else:

“We are also building a Web site that impacted customers can visit to receive their credit. We will update this post with a link to that site as soon as it is available and will share the link on Twitter through our customer support handle @comcastcares.”

“Yeah, after we forget about it in a few days,” says Stop the Cap! reader Sarah Bowler who this morning asked us about the conflicting information coming out of Comcast. “You can’t live your life with Comcast without being ready to let go of their usual screw-ups after they are fixed or else you will become obsessed. They can’t get their billing right on a good day so I don’t believe for a second they will follow through with automatic credits. Go on record asking for that credit or you probably will never see it.”

Bowler tried calling 1-800-XFINITY (1-800-934-6489) but the lines were jammed, presumably with other callers looking for outage credits or information. She eventually got her credit using Comcast’s online support website. Customers can use live chat or try calling again later.

Seattle residents are particularly infuriated because this represents the second major outage since April, when a fiber optic cable cut wiped out service for 30,000 customers for nine hours, forcing some businesses to close for the day and 911 service to be disrupted for thousands because Comcast’s redundancy plan failed.

Customers there were also told they could receive credit, but it later turned out they received it only if they asked, and even then some claim they never got it.

“Comcast spends more time alienating their customers than they work on their service,” Bowler said.

The Oscars viewing party in Shreveport nearly never happened late last month when Comcast dropped the ball and left a “Technical Difficulties” message on subscribers’ screens for several hours. An enterprising technician at a local TV station saved the day when he found old-fashioned rabbit ears and a digital tuner in the back of his truck and was able to get the local ABC affiliate’s over-the-air signal on the big screens at the Robinson Film Center.

The technical foul-up was just the latest embarrassment for Comcast, not only because the outage impacted subscribers across a 75-mile radius, but also because Shreveport has a thriving partnership with the film industry. It also may be the breaking point for city officials tired of hearing complaints Comcast refuses to fix themselves.

Comcast blamed the latest widespread outage on a power problem.

“Comcast experienced a commercial power outage Sunday night,” said Frances Smith, a representative from Comcast’s government and regulatory affairs. “We are investigating and indications are that a resulting power surge damaged the switch that transfers the headend operation to a generator. We restored the majority of service within two hours and deeply regret the inconvenience to our customers.”

No refunds or service credits for customers are planned, unless those affected specifically ask for them within 30 days of the outage.

Comcast’s 15-year franchise with the city of Shreveport expired at the end of 2012 and the company is not making any friends on the Shreveport City Council as renewal discussions plod on while complaints from subscribers continue to pour in.

Most of the problems with Comcast service in Louisiana’s third largest city relate to the length of service outages, unresponsive customer service, and the quality of cable TV reception.

Webb

Comcast officials promised upgrades six years ago to address reliability issues, but city councilman Ron Webb says he hasn’t seen them and Comcast never delivered.

“We’re not trying to run them out of town,” Webb told KTRE-TV. “I want them to provide a good service. I have everything that I own bundled with them, and I’m paying dearly for it. But I’m happy to have the service. But I just want to see those improvements. I have the same problems.”

City officials are expecting Comcast officials to appear before the city council this evening to explain themselves and report on what plans they have to fix ongoing service complaints.

As it stands, Comcast continues to operate in Shreveport on a month-to-month basis until either a new franchise agreement is signed or another cable company responds to the city’s invitations to apply for a franchise. To date, no cable company has been willing to challenge Comcast’s presence in the city. In fact, Dale Sibley, the city’s chief administrative officer told the Shreveport Times no company even responded to their requests.

Comcast’s problems have been ongoing in Shreveport for years. Last September, KTBS hinted that the city was considering replacing Comcast with a different cable operator. But as other cities have already learned, no major cable operator is willing to challenge another. (Sept. 19, 2012) (3 minutes)
