For the sake of my business I had to move everything away from Tsohost. The month long email blacklisting issues, that nearly 4 months on are still ongoing, was the final issue. Their uptime is awful to the point where none technical clients call asking to move to a host "that allows their site to be available all day". The whole refusal to provide any form of ETA for fixes to any issue was an ongoing problem. They've they've declined as a company and brand drastically in the last ~4 years.
In the end, I migrated my sites to AWS,
https://krystal.uk and
https://stablepoint.com. The difference is night and day. I no longer worry about downtime or general issues. I have a couple of servers with Stablepoint and plan to move more to them in the new year. I'm blown away by how on the ball their support staff are. Their support staff are clearly technical / server people and seriously know their stuff.
Krystal's support is also excellent, I have zero issues.
I'd recommend both of those hosts.
