Failed to verify username

Hey ok so yesterday my server was running just fine, but today it stats bugging out and now it wont even let anyone join it saying "Failed to verify username, session authentication server unavailable!
"
1. Windows 8 Pro
2. x64
3.Build 1.7.0_09
4. WAMP server
5. Build #2463
6. Bukkit GUI
8. http://pastebin.com/6MVVHJcT

 

Have you tried using a different port? As for the "Failed to verify username" bit, all Mojang services are running, so it should be good now.

It was my dns its lagging and idk how to fix it so i bought a server from NFO servers for $50 and its working properly right now thanks anyways!

 

Minecraft server got hacked today thats why it was lagging. Some punks hit is with a "DDOS."

 

Sad people. Probably some spotty skinny virgins who never leave their computer :3

 

Amen my friend, Amen.
