Today one of the site servers went offline unexpectedly, as this occured at a time when all of the site staff where at work it wasnt noticed right away and was resolved by switching in the backup server, this has been done and theres no cause for alarm etc all is good still
A side effect of swapping the site to another server is that the community patch may be displaying the messages "Backup Server" or "Site Offline", this is not the real situation as a restart will demonstrate, also the site was routing through cloudflare and so a delay in updating the sites DNS may be seen for some users trying to reach the forum, once again all is ok and this will resolve itself in a short while,
you need do nothing and continue to enjoy the fine paradise of a network we have here
