Announcements, status updates, known issues and news in general
In order to apply important software updates we will be performing rolling reboots of Xen hosts in our Amsterdam 1 datacenter.
Start: 2017-05-14 00:30 CET
Expected completion: 01:30 CET
Impact: 5-10 minute interruption for customer VMs on Xen hosts in Amsterdam 1 Pool 2 (hostnames: ams1-xen-2-*)
Thank you for your understanding. For any questions please contact support@anu.net
Update 2015-12-17: due to unforeseen circumstances this maintenance window has been rescheduled for 2015-12-21 23:00 CET.
Window: 2015-12-17 23:00 CET to 2015-12-18 05:00 CET
Reason: Change in network topology, uplinks will be reconnected to new switches.
Expected impact: None, redundant uplinks will be migrated one at a time. As with any change, there is a risk of unexpected consequences. If the Spanning Tree protocol does not correctly fail over our connection to the new upstream switch, we can expect an interruption of approximately 5 minutes.
For safety reasons, some components in the power distribution system supplying our servers in the Amsterdam 2 datacenter require replacement. This will involve 2 short interruptions to our power supply, one affecting our A feeds and one on the B feeds.
The maintenance on the A feed will take place on the 9th of November. As not all equipment connected to the A feed has the capability to automatically fail over to the B feed, we need to migrate some equipment manually prior to the maintenance window. This work will take place on the 7th and 8th of November after 19:00 CET.
Some services in our Amsterdam 2 datacenter may be unavailable for 1-5 minutes during this maintenance.
We will be monitoring our systems carefully throughout the maintenance window, however if one of your system is affected and remains unreachable for more than 5 minutes, please contact support@anu.net so we can investigate and bring you back online ASAP.
The maintenance window on the B feed will take place on the 25th November, but we do not expect any major impact during that time.
Thank you for your understanding.
