Attention Minecrafters, I have been hearing about most minecraft servers being down. If this server is down, this is why. HOICSquad has been ddosing popular servers. This was like what happened with Lizard Squad. DO NOT CALL THE FBI OF THIS. Mojang is fixing the problem. Here are screenshots from twitter.
The reason servers are going down is Minecraft has 2 new updates on new hack clients: Wolfram free edition and wolfram pro edition. Free edition crashes anyone around you using a sign and the pro edition (leaked) has a 1 click shutdown. It shuts all severs down on that port within seconds. This will not change for awhile due to Microsoft most likely making it compatible for all versions with means they can keep it at MC 1.8.7 for it to not be patched. It doesnt have anything about logins but it does tell us weak MC servers will be gone for a bit.
Its 6:44 P.M EST Where I am, and this bug is still going on. I needed to finish a build, but when I accidentally left, I knew I wouldn't be able to log back on.
