Network issue 2021-05-09

We had an issue with a core switch for our bladechassis that did not failover as it should following a fault.
Switch was still reporting functional and secondary switches did not take over as they should. This caused delay in troubleshooting process.

Effected datacenters: VBDC , interconnection between VBDC and HY
When: 12.55 CET – 13.41 CET
Component: dr-se-vb-sw02

We’ll perform software updates during night time to prevent any software causes if this issue.
If it still happens again, we’ll replace the switch as faulty.

Maintenance window / router maintenance

We will try to keep this maintenance brief but are letting you know as our valued customer.

Network dip

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)
