When attempting to file bug 823992 I received a proxy failure. On first hitting 'submit bug' I observed a long delay, followed by the following: 502 Proxy Error Proxy Error The proxy server received an invalid response from an upstream server. The proxy server could not handle the request POST /post_bug.cgi. Reason: Error reading from remote server Apache Server at bugzilla.redhat.com Port 443 The error was returned a few seconds before Tue, 22 May 2012 15:39:43 +0100 I was posting from 2001:8b0:10b:1:e6ce:8fff:fe1f:f2c0, or perhaps 90.155.92.197 if you're stuck in the 20th century. I hit the 'back' button in the browser, resubmitted and dealt with the ' It looks like you didn't come from the right page (you have no valid token for the create_bug action while processing the 'post_bug.cgi' script).' warning, and the bug was filed OK on the second attempt. Browser is Firefox 12.0 on F16 x86_64. Same proxy error was observed on submitting *this* bug too.
