Interesting how reliable Broadband has become over the last several years.
Computerworld - Japan's Internet infrastructure has remained surprisingly unaffected by last week's devastating earthquake and tsunami, according to an analysis by Internet monitoring firm Renesys.
Most Web sites are operational and the Internet remains available to support critical communication functions, Renesys CTO James Cowie wrote in a blog over the weekend.
In the immediate aftermath of the earthquake off the Japanese coast, about 100 of Japan's 6,000 network prefixes -- or segments -- were withdrawn from service. But they started reappearing on global routing tables just a few hours later. Similarly, traffic to and from Japan dropped by about 25 gigabits per second right after the Friday quake, but returned to normal levels a few hours later. And traffic at Japan's JPNAP Layer 2 Internet exchange service appears to have slowed by just 10% since Friday, according to Renesys.
"Why have we not seen more impact on international Internet traffic from this incredibly devastating quake? We don't know yet," Cowie wrote.
