We can confirm that the chesna cluster is back online & sites are loading without issue. The electrical equipment was replaced quickly by the data centre team.
Equipment replaced, servers are coming back online.
This isn't a network issue. It's an issue with the power connections to the rack that contains this cluster. Our data centre is aware & working in replacing the electrical equipment. We don't have an eta at this time. Here is the link to the issue within the data centre - http://travaux.ovh.net/?do=details&id=39180
We're investigating a possible network issue on the chesna.wpcloud cluster. This appears to be impacting a small number of sites on that cluster. Updates here once we have more details.
