UPDATE 5:20 PM Eastern 8/28/13: Forum search and New Posts functionality has returned! We appreciate your patience while we investigated and resolved this issue.
UPDATE 12:55 PM Eastern 8/22/13: We have temporarily enabled the What's New functionality of vBulletin as a workaround to this issue for now.
In recent days we have been investigating sporadic errors with DDO.com and the DDO Forums that manifest in 502 or 504 "Bad Gateway" errors. As part of our investigation into this issue, we will be disabling some Search and Advanced Search functionality. If you are not able to search in the coming days, then it is because of this action taken. Thanks! We'll try to get back search functionality to as many folks as possible, as soon as possible.
