Public PAR reverse proxies unavailability

A human error caused a configuration error on all public PAR reverse proxies which prevented them from reloading their configuration from 09:20:35 UTC to 09:24:40 UTC.

An automatic restart at 09:21:48 UTC made them unavailable until the configuration was re-generated without the error at 09:24:40 UTC.

Steps will be taken to prevent this error from happening again.
