Since around 10:00 UTC we are experience bgp session flapping on all centurylink connections. We are currently waiting for centurylink network to become stable again and convergence of all routes. Since centurylink is a major tier 1 provider convergence can take some minutes until all routes are reachable via other providers.
*Please note - servers are up & running without any issues, if you are facing any downtime, it's due to centurylink connections outage which should be stable in few time, and not everyone will face this issue
