Stable server to buy ...

[holland]

Servers from legionbox.com and hostsailor.com are attractive for me and I have to select the best one for hosting a forum, so which way is better to follow?

Servers from hostingsource.com and hostround.com are worth every cent you pay for their services.
The Support team at them is really very cooperative & active 24/7.
Their uptime is impressive, and my sites never go down.

Like GTHost.com server hosting (https://gthost.com/instant-servers/) solutions. It is very safe. They don't allow hackers to hack into other people accounts and connect with your mail account.
The combination of quality and cheapness makes them attractive for the greater part of the web masters.
