Presale Questions

Hello OVH,

Hope you all are well.

1- I know it is a stupid question but I should ask you. I want to purchase a VPS SSD service. First I want to know do you guarantee the Internet connection of your services? It is very important for me that my server doesn't be off at all.
2- Can I improve the purchased plan in the future or not?
3- Are forums the only available way of communicating with OVH support team or you've provided customers with more solutions? Email? Ticket system? Live chat? Skype? Mobile apps? etc...

Thanks for your time and patience.
All the best.
