So I'm a member of Convoy Trucking, a SAMP server, and I like the server very much. The only problem is that their hosting server, Volt, has a problem with DDOS attacks and shuts down their site and forums and the gaming server with it. People also get desynced when they're playing in the server, doing convoys, buying items at the shop, etc. It really gets annoying because you think that you're going to get to your destination safely and then you see there is no road. You're stuck, and it's because of Volt's constant DDOS attacks. I'm trying to find a server they can switch to with no problems. I'll try to suggest it to them because they are looking to switch also.
You can see they had constant DDOS attacks here: http://status.volt-host.com/
