Over the course of the coming weeks, we'll perform a migration of all customers from the servers server13, server14, server15, and server16 to new infrastructure.
Over the years we've grown and we've reached the point where investing directly in our own equipment and colocating it makes sense. This allows us to standardize on the hardware we use while also allowing for upgrading hardware such as disk space down the road without requiring migrations.
We migrate one server at a time, usually spanning 2-4 days depending on the number/size of customers on a given server.
Migrations generally start at 8.15pm every evening. There will be a short downtime during the migration. The amount of downtime mainly depends on the size of your databases.
Backups from the old system will be kept 14 days after migrations have been completed. Since the servers are new, it also means the files able for restoration for you as a customer will "reset". If you need backups restored from the old system to the new system, you'll have to contact the support for this to be fulfilled.
Customers with external DNS
You're getting allocated a specific timeslot where your migration will happen. This allows for less downtime since you know exactly when to update your DNS.
We advise that you lower the TTL to somewhere between 60 and 360 seconds for DNS records - this lowers the time it takes for DNS to switch over.
Ideally, you can make use of our DNS servers (ns1.dk, ns2.dk, ns3.dk and ns4.dk), so the migration happens automatically, and doesn't require any manual intervention from you.
We will temporarily proxy both web traffic and email traffic from the old server IP to the new one. However, this will be a maximum of 48 hours.
Migrations will be performed no later than the date informed on migration.hosting4real.net unless explicitly postponed by us. Failure to act if you're using external DNS will result in extensive downtime and possible data loss.
Avoid using our hostnames or IPs in your configuration
We generally do not recommend using naming such as server13.hosting4real.net for your hostname for either email, FTP or MySQL. For email use mail.<yourdomain.com>, for FTP use ftp.<yourdomain.com>, and for MySQL use localhost - additionally, do not hardcode IP addresses anywhere.
Customers with external whitelist requirement (payment gateways etc)
In case your payment gateway requires an IP whitelist, please use the new IP supplied within the migration dashboard (https://migration.hosting4real.net/) - this will be the IP that is used on the new servers. Alternatively, if you can specify a subnet, you can whitelist 184.108.40.206/24
