Cisco Routers to Blame for Japan Net Outtage

An anonymous reader passed us a link to a Network World article filling in the details behind the massive internet outage Japanese web users experienced earlier this week. According to the site faulty Cisco routers were to blame for the lapse, which left millions of customers without service from late evening Tuesday until early in the morning on Wednesday. "NTT East and NTT West, both group companies of Japanese telecom giant Nippon Telegraph and Telephone (NTT), are in the process of finalizing their decisions on a core router upgrade, according to the report. The routing table rewrite overflowed the routing tables and caused the routers' forwarding process to fail, the CIBC report states."

The size of the internet is not going to stop growing because many companies chose to go with underpowered Cisco kit. The internet will continue to grow by 12,000 to 17,000 routes per month, accelerating over the next few years as IPv4 space becomes exhausted and de-aggregation becomes the norm.

It sounds like what we need is legislation to enforce some hard limits on the growth of Internet routing tables in order to avoid these kinds of DoS attacks in the future. If we lobby Congress now we can hopefully avoid these disastrous consequences from reaching the United States.

Yeah, I guess now they'll be supplementing with some Belking and D-Link routers as well.
