Registration for Comic-Con 2011 tickets has been delayed at the official Comic-Con Registration website. The notification on the site reads:

WE’RE SORRY ABOUT REGISTRATION
We are really sorry for the problems with registration today. We do not know what the technical issues are, so we have temporarily closed registration.

We will announce on Monday November 8th the new date and time that registration will reopen. This down time will allow us to determine and address the issues.

Only a handful of badges were actually sold today.

Thank you for your patience, and again, we all are truly sorry for this inconvenience.

The tickets will begin being sold again sometime after November 8th. Some tickets sold out, but most remain available for the event which will have at least 140,000 people in attendance. The only tickets to sell out were the 4-day memberships including preview night access. All others will be available when registration reopens. Comic-Con 2011 International: San Diego is scheduled for July 21-24, 2011.
