If there is any unexpected issue affecting more than one Aegir instance in any location, for longer than a few minutes, or when there is scheduled maintenance, we always post updates on Twitter »
Note that we monitor real Drupal sites accessible via HTTPS entry points in our network, every minute, by checking never cached /user URL, to see if it responds with expected content, so the uptime report gives you accurate information on both Nginx server, PHP-FPM backend and Database server no-errors availability. We never pause this monitoring, even during scheduled maintenance, which means that our real average uptime is 99.99% to 100%, while reported average uptime across our global network is 99.95%
