Webspace used anomaly?

[#1]

Having uploaded a file of almost 60MB earlier I just checked usage under Website settings and it tells me only 31MB has been used out of 250MB.
There doesn't appear to be an issue with the file (it appears to be intact) and looking at ftp://ftp.plus.net/htdocs/ it also displays the filesize as almost 60MB.
On a slightly separate note is there a way of finding out if the file has been downloaded by anyone.
Thanks.

I believe the web space used figure is only updated once daily by a script that runs overnight.

Thanks for that, jelv. Couldn't see anything to indicate that on the website, though.
I'll confirm tomorrow.

So far no change - it's still showing 31MB used.

I just checked mine - yesterday and it was showing 236MB used which didn't appear to be correct (I couldn't make it add up to that big a number)
I removed a load of files and checked again today - it is still showing 236MB used which is all wrong

I refreshed the page this morning and it now shows 89MB which is about right. So it seems it's taken two days or so to update.
