The host over at my Regular-ish Site are in upgrade mode:
On May 29th, between 4:00pm and 10:00pm PST, we will be performing a few upgrades on your shared MySQL server, [name redacted].
We expect the process to take up to 30 minutes total, and once this has completed, your MySQL server will be running Ubuntu Bionic and MySQL 5.7.
You may notice that your MySQL databases are unreachable for brief periods, or your website may behave unexpectedly while we complete the upgrade. This is normal, and your sites and databases will be back online as soon as the upgrade is complete!
The full name is in fact Bionic Beaver, and this release dates to April 2018, though it should be good for four more years.
