Hurricane Sandy’s destructive forces of wind and water, combined with extensive electrical outages has wreaked havoc with telecommunications services from Maine to Virginia, leaving some customers potentially without service for weeks.

The storm has flooded Verizon‘s central switching offices in New York City, did extensive damage to Sprint’s wireless network and infrastructure, has left large sections of upstate and downstate New York without cable service, and clocks ticking for wireless cell customers using cell sites currently running on battery backup power.

Some of the worst problems are affecting Verizon’s landline and FiOS networks after the company lost two critical switching centers in Manhattan to extensive flooding. That has contributed to significant problems for Verizon customers across Manhattan, Queens, and Long Island. Further afield, Verizon customers without service can blame power outages and fallen trees that took out overhead wiring. Together, Verizon customers are experiencing significant problems with landline, broadband, and FiOS TV and Internet services in some areas.

Many Verizon Wireless cell sites are operating on battery backup units which maintain service for only a limited time. New York, New Jersey and Connecticut customers report increasing difficulty maintaining cell service signals as those battery backup units start to fail. Verizon engineering crews can restore undamaged cell sites with backup generators once permitted into storm-ravaged areas.

One of the hardest hit wireless carriers

Cablevision‘s business largely depends on areas that took a direct hit from Hurricane Sandy. Cablevision repair crews are encountering extensive power outages and damaged overhead wiring brought down during the storm in Connecticut and Long Island. Its service area closer to New York City has been primarily affected by power outages. Comcast said it was still starting an assessment process and was not prepared to report on the current state of its network, which operates in cities north and south of the New York City metro area.

While Time Warner Cable spokesman Alex Dudley reports little damage to Time Warner Cable’s systems, many remain offline from power interruptions, and Time Warner’s Twitter feed for upstate New York reports isolated outages in Portland, Maine and across upstate New York, primarily due to power losses or damage to infrastructure.

Sprint appears to be the hardest hit wireless carrier with widespread service outages, interruptions and call completion issues throughout the states of New York, New Jersey, Connecticut, Pennsylvania, Washington DC, Maryland, North Virginia and New England. Some customers far away from the worst-hit areas report trouble making and receiving calls on Sprint’s network. Many cell sites are also damaged.

AT&T is assessing damage to its landline operations in Connecticut, where it is the dominant phone company. Many AT&T cell phone sites, like Verizon, are operating on battery backup in power outage areas until AT&T can bring generators online to maintain service.

T-Mobile and MetroPCS report damage and service outages to their cellular networks as well, mostly from power outages.

Lyndhurst, NJ

Even old style communications networks were not spared from Hurricane Sandy. The Northeast Radio Watch reports a large number of broadcasters across the region off the air as of this morning:

• Outside of WOR (710), most New York City area AM stations are off the air. WOR survived the storm with its recently built three tower site located just above the flood waters. Chief engineer Tom Ray told NERW the water is 10 feet deep at WOR’s transmitter site in the Meadowlands. Many AM stations in New York favor transmitter locations in now-ravaged Lyndhurst and the Meadowlands. The result: indefinite absence of all-news WINS (1010) (it’s now back up — thanks to an update from Scott Fybush), which is now being heard on WXRK (92.3). Also missing: WLIB (1190), WSNR (620), WMCA (570), WNYC (820), WPAT (930), WNYM (970), WADO (1280) and WWRV (1330). FM outlets favor much higher transmitter locations, usually atop large skyscrapers, that escaped flood damage.
• WABC continues to air the audio portion of its broadcast on WEPN-AM (1050) and FM (98.7) for the benefit of those without power. WCBS studios are currently powered “by candlelight.”
• The Jersey shore’s FM outlets are mostly silent. Atlantic City was among the hardest hit, and some stations may be off the air for some time while rebuilding.
• Connecticut stations are also off the air. Powerhouse WICC (600) in Bridgeport has transmitters on Long Island Sound — a poor choice to withstand Sandy. It is likely underwater. Also gone: WGCH (1490 Greenwich), WAXB (850 Ridgefield) and WSHU (1260 Westport) and WALK-FM (97.5 Patchogue).

Repair crews for all concerned will likely only start assessing damage later today, but many will have to wait for power crews to complete work — they have first priority. Those lucky enough to see service restoration once power returns will be in far better shape than others who could wait weeks to get their Internet, television and phone service back.

Correction: Original story included reference to studio power knocked out at WOR-TV. That should have said WOR-AM (radio). 

NOAA caught this ominous derecho cloud front in La Porte, Ind on June 29. The same storm would later cut power for millions all the way to the eastern seaboard.

A series of severe thunderstorms accompanied by near-hurricane-force winds caused millions of customers in several Mid-Atlantic states to lose power and telecommunications services late Friday, and some are expected to remain without service until at least this coming weekend.

The storm, known as a “derecho,” uprooted trees, which in turn knocked down power lines and caused wind-related damage to buildings from Ohio to West Virginia, Virginia to Maryland, and even into North Carolina.

But the storm also is raising questions about the massive failures in commercial telecommunications systems that left entire 911 emergency response systems offline for days, wireless networks non-operational, cell phone systems overwhelmed, and broadband service, deemed a lower priority by emergency officials, down and offline.

Some of the biggest problems remain in and around the nation’s capital and in the states of West Virginia and Virginia, where inadequate infrastructure proved especially susceptible to the storm’s damaging winds.

D.C., Maryland, and northern Virginia

In northern Virginia, calls to 911 were met by silence over the weekend, thanks to a catastrophic failure of Verizon’s landline network. With primary lines down, Verizon’s backup 911 systems also failed, leaving millions with no access to emergency responders.

Fairfax County officials finally put the word out the best way to summon emergency help was to drive (through streets littered with debris and downed power lines) to the nearest fire or police station for assistance.

“It’s just not OK for the entire 911 system in the region to go down for the period of time that we were out, especially after an enormous emergency where people needed to make those calls the most,” Sharon Bulova, chairman of the Fairfax County Board of Supervisors, told the Associated Press.

Verizon spokesman Harry Mitchell was left flat-footed, promising an investigation into Verizon’s latest 911 failure, and called the storm as damaging as a hurricane. He urged local officials to “move forward” beyond the immediate criticism and help make progress to get service restored.

Many emergency response networks also depend on telecommunications services, including fiber cables, to reach transmission towers for radio dispatch and mobile data terminals. In northern Virginia, the city of Alexandria has been managing to handle emergency dispatch services for several counties.

With power lines down, cable and phone lines often went as well. In those cases, electric utilities have first priority to restore service, and then cable and phone companies can begin repairs of their own.

Since cable operators rely on power companies to supply electricity to their amplifiers and other equipment, Comcast and Cox, which dominate the region, are blaming most of their outages on power disruptions, and promise service will be restored when the power returns.

Verizon’s DSL and FiOS broadband networks were both disrupted by the storm, primarily because of downed lines and power losses.Even wireless networks, which some might suspect would be immune to downed lines, were also seriously affected by the storm. Cell towers connect to the provider’s network through fiber optic and T1 lines, and although backup power generators can maintain a cell tower for days in some cases, backhaul line cuts can leave cell towers useless.

In metro D.C., call completion problems were a problem during the storm and sometime after as local residents turned to cell phones to communicate. Over the weekend, customers in and around Richmond, Va., found Verizon Wireless useless for text messages because of a service disruption. As backup generators ran dry of fuel, some cell towers that survived the initial storm have been shutting down until maintenance crews arrive and refuel.

The harshest criticism has so far escaped phone and cable companies. Instead, local officials and residents remain focused on Pepco, the power utility serving the Washington area. Pepco has learned from previous storms to become a master of lowered expectations, and is promising to do its best to restore power a week or more after the storm was a memory.

West Virginia and western Virginia

The state of West Virginia, and western rural Virginia state, have illustrated what happens when deteriorating infrastructure is asked to withstand winds of up to 100mph. Frontier’s operations in West Virginia were hit especially hard. Landline networks in that state had been allowed to deteriorate for years by former owner Verizon Communications. Frontier had its hands full trying to keep up with repairs, calling in additional staff and trying to maintain landline service in some areas with the help of generators.

That job was made much harder by a rash of generator thefts that impacted the phone company, and local authorities are still looking for those responsible. At least one-third of all central switching offices operated by Frontier in West Virginia remain on generator power as of yesterday. As of July 3, the company reported it has 12,000 repair requests still waiting for action.

It was a similar story in the western half of Virginia where independent phone companies and Verizon were faced with an enormous number of downed trees and power lines, many in rural areas. More than 108,000 Virginia residents are still without power as of this afternoon, and many will not see it restored until the weekend.

Because the derecho swept across a large area encompassing the entire state, it has been difficult for utility crews to respond from unaffected areas to assist in repairs because the damage was so widespread. Logistically, just coordinating repair operations has proved difficult because cell service has been spotty (or networks have been jammed with calls) in some of the worst-affected areas.

“Derechos are nothing to fool with, but still this was not the most serious storm Virginia has ever dealt with, and the impacts on our telecommunications networks seem to indicate they’ve been allowed to fall apart over the last several years,” shares Stop the Cap! reader Edward Klein, who lives near Roanoke. “I think an investigation is needed to make sure utilities are spending enough money to keep these networks in good shape so this kind of thing doesn’t happen everytime a storm sweeps through.”

AT&T customers are getting no bars in more places in the state of Connecticut as the wireless company deals with 150-200 cell towers that are either without power or were damaged by a weekend storm that brought more than 20 inches of snow to some parts of New England.  But some customers are questioning why AT&T has suffered damage to their cell tower network while other carriers report no significant damage at all.

“As of Wednesday afternoon, we still have no AT&T wireless service and it takes miles of driving to find a cell tower that is still working,” reports Sam, a Stop the Cap! reader outside of Hartford.  “My friends’ Verizon Wireless and Sprint phones work as if the storm never happened. In fact, I can’t find any Verizon customer who is impacted by the storm, but that’s sure not true with AT&T.”

On Sunday, Connecticut Gov. Dannel P. Malloy noted AT&T told state officials that 152 cell towers had been damaged by the storm and that cell phone service would likely be disrupted in some portions of the state for some time to come.  But Verizon Wireless reports outside of some power outages, they sustained absolutely no damage to any of their towers and backup generators are expected to provide uninterrupted service even in areas where extended power outages are occurring.  A Verizon spokesman reported at least 93 percent of its network was operating as of Tuesday, with most of the sporadic outages due to backup batteries depleting their stored energy before technicians arrive to fire up backup generators.

Sprint also reports only minor interruptions to its service in Connecticut, mostly due to power failures.

In most cases, extended power interruptions are responsible for cell tower service failure.  When power is restored, cell service generally is as well.  But this outage proved more extensive because AT&T’s backhaul network between towers and their own facilities was also damaged by falling tree limbs and power poles.

Residents tell the Hartford Courant AT&T has made some progress as the week wears on, with slowly improving service as towers are brought back online.

“We continue to make progress in restoring service to our customers in the wake of the recent snowstorm,” Kate McKinnon, AT&T spokeswoman for the northeast region told the newspaper. “We have deployed generators and crews across the storm-impacted areas and are working around the clock to address service issues. We also continue to work with local Connecticut utility companies as they restore commercial power to affected cell sites and facilities.”

Power utility companies have first priority in service restoration. Connecticut Light & Power reports 77 percent of their customers lost power during the snowstorm.  As of this afternoon, at least 544,000 are still waiting for power to be restored.

With FairPoint Communications, customers often have to take the good with the bad.  The formerly bankrupt telephone company providing service in northern New England announced last week it had met its obligation to provide at least 90 percent of Vermont residents with a broadband option — typically 1-3Mbps DSL — and has trumpeted results showing 83 percent of Maine and 85 percent of New Hampshire is now served by FairPoint DSL, an improvement over former owner Verizon Communications, which routinely ignored rural areas in all three states.

But while winning the option to buy DSL service, thousands of customers found service lacking last week when a power cable in the Manchester Millyard area brought down both broadband and voicemail service across all three states.

In such circumstances, FairPoint’s backup generators are supposed to maintain service, but not in this case.

“I’m on dialup and went down for 10 (hours),” Wolfgang Milbrandt of Mason wrote in an e-mail to the Nashua Telegraph. “So why does FairPoint have so many eggs in the Manchester basket and is the backup power system that feeble?”

In Milford, Tom Schmidt lost his DSL broadband for about five hours last Monday, with it returning “around 6-ish.”

Company officials admitted they didn’t switch to the generator after the power failed, and customers noticed as voicemail and DSL service began to fail.  Service problems were ongoing even after power was restored after about 90 minutes, with some FairPoint customers reporting problems through the early part of last week.

FairPoint plans to press forward with DSL broadband expansion and has also prioritized build-out of its Ethernet-Over-Fiber service for cell phone towers, delivering fiber-fast connections to more than 800 tower sites to support 4G wireless broadband from major wireless carriers.
