Until your hosting service is running properly, you don’t have anything to worry about and you feel just excellent. But the real problems start when there is a problem with your hosting and you do not have any other option but to wait helplessly until it gets resolved.
You need to make sure to check what type of and how much support does the web hosting company provides. There are some companies which provide 24 x 7 x 365 days online support to resolve any of your queries at any time.
While some just provide a contact form to register your complains and get it resolved at their convenience. There are other companies which just help you with their FAQ’s and forums to resolve your issue. They aren’t quick enough to support you even when your website is facing a downtime and you are waiting for a solution.
