We all know IT can go wrong.
I have used Fasthosts in past and not had an issue but I was using a dedicated server with them. I did however later change to a different company but not due to the service. I still use Fasthost for all my domain registrations. The thing is most people forget that they need to take some responsibility for themselves as well. Regular backups and IF something is mission critical don't have it all in one place, that way if a service is affected one place its not in another and a business can still run.
The cloud is not some mythical ethereal plane of IT existence, its servers run by others, it is hardware, technology, is computers made of components and components break.
Lot of people also think hey I'll use a windows server or have their data hosted on one, well windows is as buggy as hell and has more holes in its code than Swiss cheese. Even Bill gates admitted some time ago that to go through every line of windows code and make it safe would require and entire rewrite and cost more than the product has ever made the company. DO NOT RELY ON WINDOWS.
And for those who complain about costs, look around, you can get VPN's for 5 euros or 5 US dollars a month, usually with about a 100gig ssd drive so they will be fast, often un-metered and with at least a 100mbs pipe. Get a few of those cluster them and then you have a fully redundant system if one stops others take up the slack and because they are in separate locations an outage in one place doesn't stop the others. So lets see if you had 6 at say $5.00 each a month .. thats a lot less than £60.00 a month.
If you use IT make sure you know what you are doing and MAKE BACKUPS.
Technology does go wrong so have alternative plans in place if it does. Its called being professional. Businesses used to run fine without computers at one time, so it can be done.
