At approximately 10:55PM (Bulgarian Time) our core router dropped all of our BGP sessions. Due it being completely unreachable, we were forced to perform a reboot. At approximately 11:05 the server was reachable again, after a successfull boot. BGP sessions came up shortly after. The total impact was around 15 minutes of network outage. We're currently investigating the issue, which seems to be caused by a kernel panic. The exact reason is yet unknown, however under investigation. We will keep monitoring it and apply any fixes where possible.
Should you have any questions, don't hesitate to open a ticket!
