From our hosting provider...
On 2022-02-08 between 1AM and 7AM PDT, we will be migrating your databases on shared hosting to an upgraded MySQL server.
We expect the process to take up to 10 minutes total, and once this has completed, your MySQL server will be running MySQL 8.
You may notice that your MySQL databases are unreachable for a period of time, or your websites may behave unexpectedly while the migration is underway. This is normal, and your sites and databases will be back online as soon as the upgrade is complete! You may see 30 seconds to 10 minutes of downtime, depending on the size of your databases.
