In order to increase capacity and improve performance of our Hosted Email service, we will be migrating to a new storage system hosted in our Amsterdam 1 datacenter. The initial data copy and testing has been completed, and we are now ready to perform the productions system migration. Unfortunately this work will require a disruption of approximately 2 hours. In order to minimise inconvenience, we will be performing the work during the night starting at 2022-12-07 01:00 UTC

During this time, inbound email will be queued for delivery, but access to mailboxes via POP3/IMAP will be unavailable.

Please accept our apologies for any inconvenience caused.

We will be migrating ams2-c7-1 and ams2-c6-1 Direct Admin servers from our Amsterdam 2 facility to Amsterdam 1.

This will be taking place on the 9th January at 10PM Amsterdam time – we estimate that this will be complete by 10th January at 2AM, 4 hours in total.

ams2-c7-1 currently runs on this public IP: 80.84.234.19 and ams2-c6-1 runs on: 80.84.234.13

We will be issuing each server a new public IP address. ams2-c7-1 will run on: 193.189.141.121 ams2-c6-1 will run on: 193.189.141.122

All customers who are using ams2-c7-1 (ns1.ams2-c7-1.anuhosting.net / ns2.ams2-c7-1.anuhosting.net ), ams2-c6-1 (ns1.ams2-c6-1.anuhosting.net / ns2.ams2-c7-1.anuhosting.net ) or ns1/2/3.anu.net will automatically have all DNS records pointing to the old IPs updated on their behalf.

We will forward traffic from the old IP to the new IP using a dumb proxy at the TCP/IP layer until Monday 30th January 2023 at approximately 12 noon.

We will run a scan to identify and proactively contact all affected customers where we do not have the ability to update DNS records ourselves. We advise that customers do this soon after the migration is complete to ensure the highest levels of performance and stability.

UPDATE 9TH JANUARY 2022 @ 10PM AMSTERDAM TIME:

We are going ahead with this migration as planned. Please note that due to unforeseen circumstances we are revising how long we will be forwarding the old IP until, from 3rd April 2023 at 12 noon, to 30th January 2023 at 12 noon, sorry for any inconvenience caused. Please also note that we will be maintaining the naming structure of these servers, ams2-c7-1 / ams2-c6-1, even though they will be housed in Amsterdam 1.

UPDATE 10TH JANUARY 2022 @ 1:45AM AMSTERDAM TIME:

The migration was successful. ams2-c6-1 and ams2-c7-1 are both now back online in Amsterdam 1. All DNS records we control have been updated. IP traffic from the old IP addresses are being forwarded until 30th January 2023 at 12 noon. We strongly recommend any DNS you control are updated as soon as possible for optimal performance and stability. We will proactively reach out to customers we find using the old IP addresses over the next couple of weeks.

If you have any questions, please do not hesitate to contact us by emailing support@anu.net any time!

We will be performing maintenance on our Hosted Email infrastructure which unfortunately will require a brief disruption to service.

Inbound mail will be queued for delivery once the server is back online. Access to Webmail, POP3, IMAP and SMTP will be temporarily unavailable.

The disruption is anticipated to last approximately 45 minutes and will commence at 00:00 CET on 2022-10-31

Apologies for any inconvenience caused while we perform this essential maintenance work.
