For the past hour or so a number of sites that I have with Cogent have been unreachable. Also, I am unable to get through to their support line. Is anyone else seeing this?

Just to make analysis easier: Which prefixes should be missing?

Heya,
Just to make analysis easier: Which prefixes should be missing?
We've got a feed from Cogent out of Boston and we did see a 5 minute
drop by about 5k routes in their annoucements. After that, we look as
though we're only short by around 400 or so prefixes:

There seem to be larger problems,
http://www.cogent.com returns:
Error 404 Not found
The host name in the URL you have requested "www.cogent.com" does not
match any virtual server currently running. This maybe because you
entered the host name incorrectly, or that the necessary server alias
has not been setup.

Pay no attention, I apparently don't know what I'm doing.
I think you mean http://www.cogentco.com
It's up.

That does seem to be a problem for cogent.com. To complete your analysis along those lines, you might also like to check cogentsystems.com, cogent-ssc.com, cogcomp.com, cogent.co.uk. Oh, and don't forget cogentuk.com, "The UK's largest bull stud".

Their wholesale dialup product appears to be down. A coworker just called it in and was told "multiple fiber cuts" have seriously impacted Cogent's network.
Multiple simultaneous fiber cuts...yeah, that seems likely.
