Lukanize:
This is so annoying and becoming more frequent.
Just now some pages wouldn't load or half loaded.
Lasted about 15 mins.
I had this happen shortly after 9 pm as well, pretty much right after the earthquake. Connectivity to several CDNs was compromised, though several sites loaded.
It was waiting on the WYSIWG editor on Geekzone (cdn.tinymce.com) and the site refused to load anything else. Funny, too, since it just says "Your adblock interfere with our rich text editor". Yay botched English. :\
EDIT
Also went ahead and dropped a cwtrackit.com entry into my hosts file. Sped up Geekzone load times immensely. Shame that Geekzone doesn't support subscriptions through Bitcoin anymore, though. I don't use PayPal...
