A tipster writes that his ISP blamed a service disruption on Rackspace issues.

Hey, that Rackspace outage? It also caused Internet service disruptions as far away as College Station, Texas... where I am ... my intertubes went down last night for a while, and then tonight they went out again. I just thought my ISP sucked, but when I finally got through to them they blamed Rackspace for the outages ... Apparently a bunch of services (DNS, RADIUS, etc) for SuddenLink are hosted out of there.
