[Scheduled] Maintenance on power feeds in Amsterdam 2 datacenter

During the coming weeks our colocation service provider for our Amsterdam 2 datacenter will be performing circuit upgrades to enable higher power consumption per rack. As part of this work there will be temporary disruption to our A and B feeds at separate intervals.

We do not envisage any significant impact, however some equipment without redundant power supplies will have to be moved from the A to B feed and then back again prior to the maintenance.

Time windows involved:

2017-09-21 starting at 19:00 CET, preventative maintenance to move any equipment with single power supplied from the A feed onto the B feed. No or minimal disruption anticipated.

2017-10-02 08:00 – 17:00 CET, maintenance window for the A feed. No impact expected.

2017-10-05 to 2017-10-06 (exact window TBA) – preventative maintenance to move any equipment with single power supplied from B feed back to A feed. Some short interruptions of < 5 minutes may be required.

2017-10-09 08:00 – 17:00 CET, maintenance window for the B feed. No impact expected.
