Network issue 2019.09.30

At 06:59 UTC we encountered a short network disconnection on one of our border routers. The disconnection was brief only lasting a few seconds.

After the disconnection there was a few minutes of network convergence while the BGP table reloaded.

The actual downtime for this one router was only a few seconds, however perceived downtime or unstability could be up to 10 minutes.

Core router upgrades

We are upgrading one of our routers on Sep 20 @ 05:00 CEST.
There may be some intermittent connectivity issues as BGP converges.

Update 08:10 – Upgrades are done, we are now waiting for BGP convergence on the last router and things will be back to normal.

Update 09:14 – Since 08:15 the network has been running in a normal state. At this time there should be no further issues related to this upgrade.
