Investigating - After updating packages, sites using mysqli PHP extension get 503 errors or encoding errors like:
SQLSTATE[HY000] [2019] Can't initialize character set UTF8
A possible known workaround is to switch affected sites to use nd_* extensions:
mysql to nd_mysql
mysqli to nd_mysqli
pdo_mysql to nd_pdo_mysql
Currently, we are actively investigating this issue
