Yet another nail in the coffin for TSO
I have several websites hosted with them, mostly WordPress sites, and they all run sluggishly and sometimes I get Jetpack reports that the site is down. I also use TSO as my primary mailserver on the domains.
They've been going downhill for years. If they don't sort this out I may have to shift my lazy arse and switch hosts.
In fairness to them, though, they are fairly responsive on Support Tickets and do genuinely try to help.
