[Paris] Reverse proxies requests timeout

Between 15:48 UTC+2 and 15:50 UTC+2, one of our reverse proxies on Paris unexpectedly timed out during a maintenance upgrade on our Paris zone.

The time outs last for about 2 minutes before the proxy was put out of the pool.

Some requests might have failed during the first minute and then, all requests handled failed during the remaining minute. Additional investigation will be performed to analyze what happened.
