Well I could get it again too. For several hours. But it is gone again. Along with another site that I could get all day.
We've been seeing routing sessions going up and down all over the place with major providers. This problem has removed a lot of the redundancy, and wholesale rerouting is problematic in that it is never foolproof and often errors and issues get accidentally introduced. Due to the degraded state of the topology, it is far more obvious at the moment when a network engineer makes a mistake or a piece of hardware hiccups.
This should mostly be worked out by morning. As I stated in a previous post, everybody is trying to reprogram their routers tonight to compensate. Expect the network to flap tonight while they implement this.
