We are hearing scattered reports of reachability problems affecting a small
number of remote endpoints behind a specific service provider. Only a subset
of our network appears to be affected by this. We have been in touch with
this service provider, and they have diagnosed the issue to a bad line card
in a particular router. They are presently working with their vendor to get
that card repaired.
Due to the makeup of the Internet we’re unable to effectively re-route
traffic around this failing infrastructure. We’ll make sure that this
provider drives to resolution.

The culprit very likely James Clapper, NSA Director. Thanks to Edward Snowden the cause is so obvious.
