First of all thank you for your patience during our downtime. If you have posted anything since Monday, you will need to post it again. Also if you have created a new account since Monday, that will also have to be recreated. Everyone will need to create a new password for their account.
We are very sorry for the inconvenience.
Here is a message from Epic Games CEO Tim Sweeney regarding the downtime.
Our Epic Games web sites and forums were recently hacked. We're working on getting them back up and running, and expect everything to be restored in a few days.
The hackers likely obtained the email addresses and encrypted passwords of forum users. Plain text passwords weren't revealed, but short or common passwords could be obtained by brute-force attack. Therefore, we're resetting all passwords. If you have an account on the Epic Games forums, you can request to receive your new password by email it to the address we have on file for you.
The Unreal Developer Network (UDN) has not been compromised. None of our web sites ask for, or store, credit card information or other sensitive customer data.
We're sorry for the inconvenience, and appreciate everyone's patience as we get our servers back under control.
