1337pwn.com had a regular process that monitored the amount of activity on the site. As we've moved from several hundred thousand hit/day to million hit/day territory, that process can no longer keep up. It's been taken offline as it was the cause of two short outages during the past 3 days.
Thank you for your patience.
UPDATE:
We later discovered that these outages were caused by an application scraping our feeds and calling so frequently as to effectively create a DoS attack. Our hosting provider made changes to put a stop to it.
