Purple is moving to a new data centre this weekend. As part of this, its IP address is changing.
In general, there’s nothing you need to do, unless you manage your own DNS records and point your entries at purple via an A record (IP address). In an ideal world, you should CNAME your entries to “purple.alexlomas.com” however, if you need to create an A record, please now point it at 18.104.22.168
The DNS entry for purple.alexlomas.com will be updated tonight and the server move itself will take place from about 0800 tomorrow morning, finishing by midday at the latest. It can take up to 24 hours for cached DNS entries to reflect these changes.
This should hopefully be the last move for some time and will bring better speed and reliability.
