We will be replacing a switch between the hours of 6pm and midnight (CEST) on Tuesday 23rd October 2018 in our Amsterdam 2 DC.
We expect network downtime to be very minimal – no individual server or service should be without network access for more than 60 seconds.
We apologise in advance for any inconvenience.
Urgent maintenance work is being performed on the storage subsystem of our mail.anu.net server.
Webmail, POP3, IMAP and SMTP services will be unavailable for approximately 25 minutes starting at 20:35 CET
Our apologies in advance for any inconvenience this may cause.
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.
