One of our network upstreams has announced network maintenance.
Please note that routing changes may cause momentary traffic dip during this time frame.

Our own traffic should automatically failover to secondary ISPs.


Date and time for maintenance window
Start date and time: 2020-05-05 03:00 UTC
End date and time: 2020-05-05 04:00 UTC

At 04.30 we performed a reboot of one of our core routers to ensure the issue is not on our end.

We will reboot some other equipment to troubleshoot issues.
We apologize for the disruption.

Update: One core switch was also rebooted manually at 05.50 – 05.52 . (short dip)

We have made adjustments to network traffic to find a stopgap solution to flapping network connection.

One of our upstream transits suffered an outage at 19.05. This caused network re-routing to happen and may have been felt as momentary network dip.
Traffic has been re-routed to failovers. We’re monitoring the networks.

When: 19:05 – 19:10 (upstream has failed over)
Impact: 5min re-routing, traffic dip
What: 46.253.192.0/20

Update: Some more network dips occured during the evening. The network upstream suspected of causing high CPU usage in our cores have been isolated. We’re continuing to monitor the situation.

When: 20.30, 23.30 , duration (roughly 2-3min per incident)
