[Complete] ams2-c7-1 & ams2-c6-1 Migration

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: and ams2-c6-1 runs on:

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

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.


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.


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.

OpenVPN Upgrade

We are rolling out an upgrade to our OpenVPN server – replacing a primary/backup configuration with a high availability cluster of servers. If the primary server ever goes down, a secondary one can immediately take over and continue to serve traffic as normal.

We are mitigating the VORACLE attack vulnerability at the same time (CLICK HERE) by disabling compression. This is now deprecated and will be removed from OpenVPN soon. This is to protect against a hard to exploit but theoretical idea that you can extract certain information from encrypted traffic by how well it compresses. Unfortunately, this change means that existing client configurations can’t automatically connect to the new servers as compression is explicitly specified.

All clients connecting will need to download a new OpenVPN profile containing the new server addresses and without compression specified. Click HERE to begin this process – you need to know your VPN username and password. This will connect you to our new servers and you’ll be ready to go.

If you would prefer, you can manually edit your config file, changing ‘openvpn.anu.net’ to ‘vpn.anu.net’ and removing any line stating ‘compress lzo’ or ‘comp-lzo’.

We plan to keep our old OpenVPN server running for 6 months – it will be shut down Monday, 10th October 2022 at 12 noon.
