Webhost4Life - serious issues

For several years (yes, years) I have been using a host called webhost4life.

I chose them after some disastrous trials with other hosts - they were good value, fast, and had excellent tech support. I happily recommended them to anyone.

That was then.

Now, in the last 7 days, something dreadful has happened. They have migrated my site onto a new platform, and broken huge chunks of it in the process. Without telling me. I host around ten sites, and most are now broken, damaged, or limited in some way. Forums fall over, scripts don't work, links seem to have been automatically changed by a script to point to (incorrect) pages!

This is my data. These are my live sites that they have taken it upon themselves to alter and break without notifying me.

I'll post again soon when I am confident of doing so without saying too many rude things. Angry? Don't even start...

Initial research shows that I'm not alone. This is huge:

Fishwise site broken by webhost4life
Webhost 4 life - down the pan
Goodbye webhost4life

I shall be moving as fast as I can to a new host. Suggestions?
