The issue, at least for me, appears to be with Comcast. I've confirmed that Google is accessible on both Verizon and T-Mobile networks.

Since I happen to be working on a web application with several scripts pulling from Google's CDN, I needed access to it. Assuming you have a server that is not on Comcast's, you should be able to setup a simple SOCKS proxy and tunnel your traffic through it:

ssh -D localhost:6772 username@hostname

Assuming OS X as your OS, go under Network Preferences -> Advanced -> Proxies, check "SOCKS Proxy" and enter the host/port.

From there, your internet traffic should be tunneled through the server.

Ok google was down and they cite a couple funny tweets about how the world is going to end. Anything else that's of interest here? Google's not gonna tell us how it was caused (they're too cool for that)...

The server for http://www.google.com/webhp?hl=en took too long to respond. It may be overloaded. Error code: 504

They're right about the Southeast; here in Florida all the services I tried are dead, except I can ping Google.com.
