Ike Hammers Texas Internet

Renesys reporting on the effects of IKe, especially in Houston:

>>The counties around Galveston and Houston, TX (most notably Harris County) have suffered a slowly climbing number of network outages over the last day. We expect to see this number continue to climb as the secondary effects (e.g. power loss, UPS battery failure, generator fuel unavailability) of the storm hit the region.

We examined the withdrawals reported in BGP for prefixes (networks) in Arkansas, Florida, Louisiana, Mississippi, Oklahoma and Texas and notice that, aside from Texas, the coastal Gulf region has fared pretty well against Ike, so far. The Texan cities and counties immediately in the path of Ike are, however, definitely and noticeably suffering network connectivity failures.

Affected cities, counties and organizations

To get a sense for the organizations affected in the initial aftermath of Ike, we can look at the top ten organizations, top five cities and top five counties, sorted by number of networks suffering an outage as of approximately 13:00 CDT. Notably, these do not account for the relative sizes of the organizations, cities or counties.
