The January downtime is complete.

 Please take note of the following changes and submit a ticket to CCR Help if you are experiencing problems:

What has changed for users:

• Home directory quotas are being increased to 5GB from 2GB
  
• Modules software has been updated - should be transparent to users but see this knowledgebase article for more details
