America) they always seem to have a really short age header. Doing ?action=purge doesn't seem to have any affect on clearing things, I don't know what that means. I think the real issue is at the MW/Swift layer though. -- You are receiving this mail because: You are on the CC list for the bug. You are the assignee for the bug.
