Currently, whenever I open a new page containing any Stack Overflow content: main page, tagged questions, an individual question, user profile, anything, all content is completely unstyled, as if all CSS was removed. I did View Source, and this style sheet reference is present.

<link rel="stylesheet" type="text/css" href="http://sstatic-a.akamaihd.net/stackoverflow/all.css?v=fca729ed9ab4">

Navigating to that site, I can see that my company blocks content from that site.

Meta Stack Overflow is not affected; the CSS link here in Meta appears to be locally hosted.

<link rel="stylesheet" type="text/css" href="/content/stackoverflowmeta/all.css?v=36683b668064">

I've seen this behavior before on Stack Overflow. Is this another test? How often are these tests? Will the tests stop at some point?


All CSS content appears to have been restored on Stack Overflow. The CSS link has changed to

<link rel="stylesheet" type="text/css" href="http://turbo-test.cdn.sstatic.net/stackoverflow/all.css?v=fca729ed9ab4">

    Your company firewall blocks Akamai CDN resources?! Apr 12 '13 at 17:15
  • @MartijnPieters: Not the firewall; it's WebSense. Reason: This Websense category is filtered: Streaming Media.

  • WebSense is a firewall., Apr 12 '13 at 17:18

We are testing several CDN candidates at the moment in 10 minute intervals - we'll be stable again in a bit. We want to deliver the content to you guys as fast as possible, so we're seeing what options perform best.

  • For some reason chat(on all three sites) isn't working for me (Connection timed out). Is this related to the CDN issue? Apr 12 '13 at 17:35
  • @Manishearth - nope, chat is undergoing no tests and is working normally on our side. Apr 12 '13 at 21:20
  • Ah well. Anyway, it stopped breaking -- probably something screwy on my end. Apr 13 '13 at 2:45
