It's most likely on my end, but I can browse the web just fine, but for some reason I can't access either Facebook or Twitter?! I can do a google search, and no issues with any other sites I've tried browsing to so far.

I'm home, and not behind a proxy of any kind.

Hmm, seems to be a DNS issue on my end.

No problems here, good luck

OK so I restarted my domain / DNS server (it had some Windows updates) and I restarted my DNS service.

Facebook and Twitter still don't work for me.

I went to the website "Down For Everyone Or Just Me?" and it's telling me it's not just me. FB is down?!

I just logged on to Facebook no problem (from Vancouver, B.C., Canada).

I was able to get to twitter.com, but I don't have a Twitter account, so wasn't able to test further.

Looks like it's only affecting the United States right now.
