At approximately 8:30pm CST, our Arizona USA network began experiencing heavy traffic most likely originating from a DDoS attack. Our Arbor Networks firewall will activate within minutes to mitigate the attack and we expect to have full access to all affected services within an hour. All Minecraft servers on the affects systems may experience lag and/or downtime while this takes place. We apologize for the inconvenience.
Note: This notice excludes Node 30 USA.
Update @ 9:35pm CST: It appears the attack has stopped and all services should be back to normal.
Please do not submit a support ticket about this problem.
