Google Went Down Because of DNS Misconfiguration

Have you ever tried to hit and gotten a 404? Me neither. But check this out:
Brief Outages at Google, eBay Make Headlines

Now I've been to Google and I've talked to their DNS guys. I know they use BIND as well as djbdns. For those of you who don't know, BIND sucks, but that is another story. Still, I have to wonder whether there was some kind of hack on Google's DNS servers or whether to attribute this to human error.

Some supposed answers to this question:


Google (NOT) Hacked? Just A DNS Glitch says Google

Statistically human error is more likely to be the root cause of any outage but there are some interesting factors at play here. First, Google has arguably one of the most complex DNS configurations of any internet company. Second, Google has some of the best sysadmins of any internet company. Third, this happened at 5 minutes to midnight on a Saturday night. Cron job anyone?

No matter what happend its pretty remarkable.
