[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.

[Complete] Planned upgrade of PHP for Managed Web Hosting accounts

Update 11:34 Sorry for the extended outage. We are happy to report the server is now back up and running with Apache 2.4.10 and PHP 5.6.5

Update 11:23 Apache and Lasso are back up and running, PHP sites currently still returning Internal Server Error.

Update 11:17 We are making progress but have run into a few unforeseen issues that have caused unexpected downtime. We expect to be up and running again within a few minutes.

Update 11:08 The upgrade is in progress, please bear with us.

Our Managed Web Hosting accounts currently run PHP 5.3

Version 5.3 has been end of life for quite some time and is no longer being actively maintained. Some new PHP software now requires version 5.4 or higher in order to run. We are therefore planning to upgrade PHP.

We have tentatively scheduled this for Monday the 26th of January at 11:00 GMT

Loading the new version of PHP will require a restart of Apache but otherwise should be very straight forward and only cause a few seconds downtime.

Please take a moment to ensure any software you are running on our Managed Web Hosting or Reseller Hosting accounts, such as Magento, WordPress, Joomla or Drupal is up to date and is compatible with PHP 5.6.

A list of deprecated features and backwards-incompatible changes for each version can be found at:

We will be on hand during the day on Monday, so please test your sites post-upgrade and if you find any issues please email support@anu.net and we’ll do our best to help resolve them.
