It looks like several Web 2.0 services are having problems now.
Twitter is down. According to their status blog, it's a denial of service (DoS) attack. "We are defending against a denial-of-service attack, and will update status again shortly." Some say Twitter Search works, but I can't get it to load.
Facebook is experiencing intermittent outages. Error messages like this:
But there's little evidence of a DDOS aimed at FB. Overflow from Twitter could be partially to blame.
Livejournal is also going on and off. Their status blog claims a DOS earlier this morning.
Updating as news comes in.
Possibly overflow from Twitter is hurting the others. I've already used Facebook to post about Twitter.
Infocult angle: these outages, especially coming at the same time, could be the basis of a series of rumors and fears.
