We have received a report of the Cogent Data Center in Herndon, VA having connectivity problems.  It appears to be localized.  No need to innundate them with phone calls, I am sure they are working on it.

One of our readers, Colin, called into the data center:  "I called their support staff and got through to a guy who described the situation as a network problem 'affecting all traffic in their data center'."

More on this situation if more develops...

Update #1

It appears that sometime on Wednesday that the problems were more widespread, as they had some latency problems up in New York as well, as reported by another reader.  However it appears that the problems had been resolved as of Thursday.  No report yet on if the problem at the Herndon, Virginia office has been resolved.

Update #2

It seems like the Cogent outage was just some scheduled maintenance that they were performing on some of their fiber links.  The problem has been resolved.
