Yup. Sad day and end of an era.
I went over to TSO but there was no noticeable change for me, as mentioned in that thread Vidahost was still run separately/independently for those with their own servers, so I didn't really notice much difference.
Not too happy about the GoDaddy merger but they seem to have left my server along as it was despite it being a bespoke build package. They probably don't even know from looking at it on the rack that Dom would do things like put extra RAM in. I did start looking around last year when my annual fees were due, but it does seem difficult to find decent UK hosting with Cpanel that doesn't cost the earth.. but then I also had my own health issues.... and don't know if I want the hassle of moving.
Vidahost were always good at informing about scheduled maintenance or even just general news.. but now there's no correspondence apart from billing.
Like I said above tiny fish in a large pond.
