Good to see you last Thursday. My scripts have some failures now. A merged DB of my results can be grabbed from here[1]. The results are from 2 machines (crisp and dwarf), one in the US the other in the UK; and they use different network configurations (DNS et al.) too. The bulk of failures are connecting to 'meta' and most of those responses are of form '500 SSL read timeout'. The last two responses (one on crisp and one on dwarf) are 'HTTP/1.1 503 All backends failed or unhealthy'. There is one 'HTTP/1.1 502 Bad Gateway' too. Table [2] gives a summary of the failure times. The failures are not always paired but where one machine fails there is a high likelyhood a "close to concurrent test on the other machine will also fail. This and the repeated failures on both machines (different network paths) between 2014-08-03 04:10:32 and 2014-08-03 04:22:32 leave me thinking this is a server side issue (eg. Mirror synching (as mentioned before), lockouts due to system and/or DB backups, too many connections etc).
