I noticed unavailability of some sites through our UUNet connection as well. Trace routes showed that the packets were being dropped after it was passed onto above.net but also before that. I assume not only was above.net having problems, but I screwed up UUNet's routes they received from them. A call to UUNet didn't help. The tech, though nice, had no idea what to look for. I was sitting there giving him commands and asking the result. After I figured everything was ok between us, I figured it was bigger than just my connection and waited patiently. All was good within 15 min or less.

I have been noticing several UUNet problems recently. My Oakland office (connected via UUNet) and my company's service bureau, run by a contractor company (also UUNet) had problems seeing my main corp. web server colo'd at Hurricane Electric, yesterday. Turns out there was a DoS attack ran against a router on above.net (which provides the peering between UUNet and HE).

However, I have also seen problems with customers being unable to see my contractor's machines. Supposedly, there are some rather strategic DoS attacks going on. Can anyone confirm this?
