As per the announceent posted in our status page about the upgrade for the server SG09 - the upgrade is now all complete as of now.
The upgrade is part of our move to fast NVMe storage. The new server includes fast AMD EPYC CPUs, NVMe storage, and updated software providing improved performance. No action is required at your end if the domain do already point to our nameservers - however, for any domains pointing to Cloudflare or any 3rd party DNS resolvers, an email is sent with the full details. Please do follow through the same and update the records as soon as possible (even though we do have a proxy which will mean the website will remain operational for up to 7 days even if the changes are not made)
You can find the full details about the same under "Incident History" on our status page here:
Any future upgrades would also be posted on our status page and would be available under "Upcoming Maintenance" as the timing for their initiation is confirmed.
