My site went down on Hostinger and they tried to tell me it was me who had the problem, around 12 hours later they realised it was their end! 5 days later it was still down and I had limited access to my back ups as they were having problems with the main servers and back up servers and I emailed them a few times only to be told 'I had to be patient while they tried to solve the problem'.
I moved to a new company and it took them a few days to access the backup files due to the server problems. I have no idea how long Hostinger was down for in the end, not even an email from them to apologise.
