I can post on meta with no issue. But for some odd reason I am not seeing the full-blown Stack Overflow site. It appears the CSS is missing from most of it.

Enter image description here

When I try to hit the CDN at this link, this is what I get:

The webpage at cdn.sstatic.net/stackoverflow/all.css?v=8a7874f4f2dd might be temporarily down or it may have moved permanently to a new web address

  • it's probably an issue with out CDN. please refresh. – Sklivvz Jul 3 '13 at 13:47
  • been refreshing all day and rebooted and cleared cookies. – JonH Jul 3 '13 at 13:48
  • Just got the problem 3 times in 1 hour. Refreshing doesn't solve the problem. You just have to wait. – Kees Sonnema Jul 3 '13 at 13:51
  • @JonH Great! A friend of mine had the same problem like an hour ago on all of his browsers and asked if I had the same problem but I didn't. It went away after a while but this certainly is some kind of bug. – Daanvn Jul 3 '13 at 13:51
  • Been trying since 7am with the same issue. – JonH Jul 3 '13 at 13:52
  • @Jon browse to this link directly... what you get? – Shadow The Princess Wizard Jul 3 '13 at 13:53
  • The webpage at cdn.sstatic.net/stackoverflow/all.css?v=8a7874f4f2dd might be temporarily down or it may have moved permanently to a new web address. – JonH Jul 3 '13 at 13:54
  • Maybe ipv6 problem then, see here – Shadow The Princess Wizard Jul 3 '13 at 13:57
  • Working okay for me... – zigojacko Jul 3 '13 at 13:57
  • @Jon another one... go to this test page if you have ipv6 address detected you might need to disable it as described in the other post. – Shadow The Princess Wizard Jul 3 '13 at 13:58
  • I see this occasionally and it seems to just be connection blip related - the CSS couldn't load for whatever reason (usually when I'm connected to a slow VPN). In this case it sounds like you have a more serious issue - from your end the CDN is down. – Aaron Bertrand Jul 3 '13 at 13:58

    Jin has been hard at work on the new "craigslist style" redesign. – Bill the Lizard Jul 3 '13 at 14:09
  • @anyone - has any of the developers @ stackoverflow or mods had a chance to look at this? – JonH Jul 8 '13 at 18:50
  • @JonH can you send me a traceroute please? craver@stackoverflow.com – Nick Craver Jul 8 '13 at 19:36
  • @NickCraver - Thanks I just sent you a trace route. – JonH Jul 9 '13 at 11:57

We ended up resolving this although it was not an easy solution. We were using EdgeWave's iPrism to authenticate users out to the web. It's not a proxy and it definitely wasn't blocking Stack Overflow or even the CDNs. The issue was the CDN IP address seemed to be changing and we think the iPrism thought this was some sort of spoofing. In any event we managed to add the IP addresses given to us by CloudFlare as exceptions within the iPrism interface. Once we did that Stack Overflow was working.
