There seems to be a bug in the way storage limits are checked.

I set an account with a limit of 1GB

I then deliberately stick a file on there thats 2.1GB big thus putting it way over the threshold of the account limit.

I leave this on the server and can see Centova has seen it's over the limit and stuck it as RED on the account

I delete the file and leave it for a few hours, yet it's still RED. I'm unsure what the cron job times are for the script that manages this feature.

Also noticing a strange number glitch
On the main admin panel I see - 2.1/1G
Yes when I go into that account I see - Disk usage: 2.15/0.98GB

Disk quota is updated nightly, as with all prior versions of Centova Cast.

That's not a glitch, that's rounding.  In some places the quota is displayed to one decimal point, and in others two, depending on how much screen real-estate is available.
