Customers Shocked By Level 3's Internet Disruption

Level 3 Communications said it warned partners before pulling the plug on some of the pieces of the Internet backbone that it controls. Although the connections are back on, temporarily, the company remains in a snit over shared bandwidth usage.

Level 3 Communications said it warned Cogent Communications before pulling the plug on parts of the Internet last Thursday. But not everyone received an alert.

Partners of the two Internet communication companies said they and their customers were taken completely by surprise when Level 3 cut off the free peering connection between it and Cogent, which severed access to tens of millions of IP addresses. Peering is a common practice that Internet backbones such as Level 3 and Cogent use to give customers the simplest access to all of the Internet.

Level 3 has temporarily restored the peering connection, though it remains in a heated spat with Cogent over shared bandwidth usage.

Tim Bradley, senior vice president of VoIP at New Global Telecom, a Level 3 master agent in Golden, Colo., said the sudden shutdown of major parts of the Internet caught him and his customers off-guard. "We were given no prior warning. We learned about it from a sudden burst of sporadic customer calls," he said.

The lack of advance notice about the shutdown from Level 3 didn’t please Bradley. Customers calling New Global Telecom about the service interruption expected the company to know what was going on, and customer service staff had to scramble to stay on top of things, he noted. "We very calmly and very coolly took care of everyone," he said.

Such an abrupt Internet shutdown isn’t very likely, so building in redundancy for such an event--be it adding a failover network via a second Internet provider loop or a firewall that redirects IP traffic--isn’t something that’s high on anyone’s checklist, according to Bradley. In fact, most of New Global's business customers just happened to have both a Cogent loop and a second Internet provider loop, "so the impact was minimized," he said.

Yet one of Cogent's largest customers wasn’t so lucky, said Quy "Q" Nguyen, founder and CEO of Allyance Communications Networks, Irvine, Calif.

The customer, an online gaming company that has needed to increase its bandwidth monthly, saw its Internet traffic drop at least 25 percent when Level 3 pulled the plug on Cogent, said Nguyen. And the gaming company had no failover in place. "They were just down," Nguyen said.

Another Cogent customer, which lost 50 percent of its Internet traffic when Level 3 cut off Cogent, was quickly convinced by Level 3 to leave Cogent and sign a one-year contract, said Nguyen. "Then, only minutes after they signed the contract, [Level 3] announced they would turn back on the peering connection. Now they're stuck under a one-year contract at $25 per [megabyte], when they were paying $10 per meg with Cogent. They told me as soon as the contract is up, they are leaving Level 3," he said.

Sureel Choksi, executive vice president at Broomfield, Colo.-based Level 3, said in a statement that there was nothing sudden about Level 3 cutting Cogent's peering connection. At least three times over the past three months, Level 3 warned Cogent that it would take such action if the two companies couldn’t negotiate "alternative commercial terms to allow the continued exchange of traffic," Choksi said.
