Update your Minecraft server for 1.6.4!

1.6.4 was just released to the launcher! If you’re running CraftBukkit with plugins, we recommend waiting until they release a stable build before updating. If you don’t mind playing vanilla for a while, or you’re already running a vanilla Minecraft server, here’s how you can update:

  1. Stop your server
  2. Delete the jar/minecraft_server.jar file from your server via FTP. (Be sure you don’t have a custom JAR name, and be sure you’re deleting from the “jar” folder)
  3. Make sure your JAR file in Multicraft is set to the correct version; this should be “Minecraft (Vanilla)” for 1.6.4.
  4. Start your server!

If you’re running CraftBukkit 1.6.2 and you want to update to 1.6.4 dev, follow the above steps with “craftbukkit_beta.jar” and using the “CraftBukkit (Dev / Latest)” option in Multicraft.

If you’re running CraftBukkit and need to downgrade your client to play, follow these steps:

  1. Open Minecraft
  2. Click ‘Edit Profile’ in the launcher
  3. Select ‘Release 1.6.2’ in the ‘Use Version’ section
  4. Save and login!

If you run into any trouble, just submit a support ticket and we’ll get you set up.

London, UK Network Routing Issues

Update: Latency appears to have returned to normal, we’ll keep an eye on it over the next few hours and update this post if anything changes.

At around 17:00 UTC (12:00 PM CDT) today part of our UK network began experiencing severe routing issues causing very high latency and packet loss. This is caused by an error between a global network carrier and our datacenter; these types of problems must resolve themselves over the next few hours. Once the servers are fully accessible again, we’ll update this post.

The following systems are affected:

  • Node 8 London, UK (node8.ln.uk.mc.cubedhost.org)
  • London, UK SQL (ln.uk.sql.cubedhost.org)

France Multicraft Maintenance

Update: The maintenance has been completed. Your server’s name, jar file, world name, and some other misc. settings may have been reverted/changed. If you have any trouble accessing your Multicraft panel, please submit a support ticket.

We are currently performing a maintenance on our France Multicraft panel and MySQL over the next 24 hours. If your server is inaccessible, simply submit a support ticket and our team can get you squared away ASAP.

Minecraft Security Advisory – Authentication Exploit

The following has been emailed to all active and/or suspended CubedHost Minecraft customers.

** Please note ** Absolutely NO CubedHost services have been compromised. This is a general Minecraft security advisory.

We have recently become aware of a (working) exploit for the Minecraft protocol, that is a high risk to any server that is in online-mode and using an older CraftBukkit / Spigot build, or vanilla Minecraft.
This security exploit essentially allows for any user to authenticate as any player on your server. We have tested this exploit, and it does indeed work, making this a fairly high security risk.

Further details can be found via Reddit, Planet Minecraft, etc.

We recommend that you update to the latest version of CraftBukkit / Spigot immediately.
As far as we’re currently aware, there is no fix with the Vanilla Minecraft server as of yet.

To update your server, please follow this knowledgebase article.

USA Maintenance – Sept. 4th/5th

[4:45AM CDT] Update: Node 13 Arizona is now back online. Performance on this system should be significantly better, as the failing motherboard has been replaced. Thank you for your patience.

[1:12AM CDT] Update: The USA software update maintenance has been completed successfully, with less than 5 minutes of downtime per node. If you have trouble connecting to your server, please submit a support ticketNode 13 AZ is still undergoing hardware maintenance. We’ll keep you updated on that situation.


As we noted in our previous post last week, we’ve scheduled a planned maintenance to replace the second CPU in US Node 13 AZ (Phoenix, Arizona). The downtime may be up to 1 – 2 hours, but hopefully it will be quick.

In addition, we have an additional planned, USA network-wide maintenance as noted in an email sent out in the past 24 hours. Downtime should be fairly brief as we’re only doing minimal software updates. These downtimes will be rolling, starting with Node 1 AZ and ending with Node 8 VA.

Both maintenances start at 12AM CDT (Sept. 5th). We’ll keep you updated with the details.
