Last sunday i had a similar problem for several hours, but since then i've been able to access the site without problems.

The trace route i took on sunday looked very similar to yours, this is the current traceroute :

I have heard of similar problems accessing some US sites over the past months , and it appears the problem occurs when one or more of the routers along the route are under heavy load.
In this case it would be the routers in the 154.54.x.x part.

As enduser there seem to be only 2 options :
- wait until the route works again (waiting period can vary between a few minutes and several days)
- use a proxy in a different country so the site is accessed over another route (hopefully one without problems)

Edit : for some reason it's usually europeans who have this trouble

I've had the same problem for 2 days, I just got it back a few minutes ago. It's the second time this happens, I really wonder what might be causing this...

I had the same problem this weekend, it "solved itself" yesterday (nov 19) afternoon. My traceroutes also indicated problems with (or maybe rather one hop beyond) a Cogent router, in my case g14-0-0.core01.iad01.atlas.cogentco.com (154.54.5.57). I tested tracerouteing to www.archlinux.org from different locations using their Looking Glass, and noticed that all Europe routers except for one of them (I think it was the one in Amsterdam) could get to www.archlinux.org.

Anyway, I just wanted to say "+1" and point to the Looking Glass page (for people to test in case this happens again)

The problem was with cogent.
The "solving itself" was cogent fixing their problem.

finferflu · 2007-11-20 23:31:24

Thanks cactus, now I feel a bit better since I know where the problem was

Yes, of course it was, if it sounded like I implied otherwise, I apologize.
