What does it mean to have your slot locked?
Slots are locked (suspended) when there is a problem that needs to be solved. While a slot is locked the client is shutdown and FTP and SSH access is blocked. In most cases the problem can be quickly resolved allowing us to unlock your slot. There are several reasons your slot may be locked:
Reasons for locking slots
You haven't paid for your slot. Your "days remaining" can be seen on the Manage page. You can fix your balance by paying via that page. After payment your slot should automatically get unlocked. If you believe your remaining time is incorrect, let us know.
You're using too much disk space
It's your responsibility to keep an eye on your disk space usage. If you have been locked for disk space overuse, you may want to consider upgrading your slot. To get your slot unlocked, file a ticket letting us know whether you want to upgrade or whether you will delete files.
