For me it must be:
1. Ensuring reliable service to the customers
2. Ensuring security and privacy of systems and network, as well as the networks and systems of others
3. Should have the maintenance reputation as a responsible service provider
4. Should preserve the privacy and security of individual users
5. Should have the intensity to provide its customers access to everything the Internet has to offer.
I think this might be helpful for analysing out the hosting provider
6. Should do backup as often as possible.
