I’m unable to get any Stack Overflow, Super User, Server Fault, and security.stackexchange pages displayed correctly if I’m logged in (maybe this list is incomplete).

After looking at my debugging tools, I found the CSS fails to load correctly, because I’m getting a 409 response.

More information:

Hopefully, Meta Stack Exchange works, but I can’t reply to comments on the targeted web sites. Please fix this!!!

  • CDN problems are most often caused by localised issues with CDNs, that's what they're for. Knowing which part of the world you're located will help determine the source of the issue.

  • @Oded : anyway, as you can see it on the second screenshost, the issue is with CloudFlare.

    @user2284570 See the edit to my answer. If you can get the dig output as well, that'd be great.

    @Quill : stop trying to change the question title : Not all Stack Exchange sites are concerned. And writing internet without starting with an upper case letter is valid in ᴜᴋ English.

    People are trying to help by improving your grammar and readability. Too bad you don't accept it and keep reverting their correct changes.

We aren't using Cloudflare anymore as of a few weeks ago. I realize that's what the screenshot says... but something on your end isn't resolving cdn.sstatic.net correctly.

Can you post a traceroute output from your machine to cdn.sstatic.net?

(Correction... apparently what would actually be helpful is the output from dig +trace cdn.sstatic.net. I don't know much about getting it installed/running on Windows myself, but there are some instructions here).
