central installer server check
Sophos Central Installer checks server availability. Somehow that check was passing during last week's outage when Sophos servers were not able to complete installation and protection. The installer's checks should verify that all resources are available for protection to succeed, so that the installer is not able to uninstall existing protection and then fail, leaving endpoints unprotected. Moreover, Sophos needs a switch to flip to force this check to fail the next time they have a catastrophic outage like they did 11-14 July.
