Planned maintenance work 2021-06-20

When: Sunday 12.00 – 18.00 on 2021-06-20
Why: Datacenter facility provider maintenance
Affects: Hammarby Datacenter, Interconnect between Hammarby DC and other datacenters
as well as other services on hosting range

Our datacenter provider GlobalConnect are performing structural integrity improvements in the facility. This requires us to move equipment in the zone we’re located in. We’ll be doing this with ”construction electricity” to avoid powering down the equipment.

We need to move some uplink cables, which may cause momentary interruptions.
Our intention is that the disruptions will only last minutes at a time, but we’re still announcing a service window. Please plan your activities and services according this this service window.

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.

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

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)
