[Rescheduled] Scheduled maintenance in Amsterdam 1 datacenter

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.

[Completed] Scheduled maintenance in Amsterdam 2 datacenter, 7-10 November

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.

[Resolved] Packet loss from some locations

As reported by network operations at our Amsterdam 1 colocation facility:

Type: Unscheduled
Start Time: 2015-06-12 10:45 CEST
End Time: t.b.d.
Location: n/a

Impact: We are currently suffering from degraded performance on one of our IP transit providers. The issue is under investigation. Customers might notice packetloss to remote locations.

Update: This seems to be a global issue. To partially mitigate this issue, we have temporarily disabled one of our transit providers. Please note that other ISP's around the world might suffer from the same problem.

This issue also appears to be affecting many customers hosted in our Amsterdam 2 facility. USA, Singapore, Dublin and Munich are not affected.
