Looks like you inadvertently stumbled on the first step in bug triage - show it to someone else and it'll work perfectly. I've done it so many times myself.
My first thought when reading of your troubles was that some crucial Google server had gone down - and now it's back up. But it's hard to say. Very squirrely, this Internet thingy.
