Best to my knowledge this website is on box 13
You should ignore the Box numbers on 110MB's ErrorDocuments, they're only related to 110MB's current convoluted ErrorDocument system.
Box 13 changed it's IP on 26 February (suggesting the server has been successfully wrested
from the grasp of 'Burst'), but neither FTP or Control Panel have worked since that date.
I cannot explain why your links
don't work, but if your site is MySQL dependent you might find that MySQL is currently inoperative on this server. Personally, I don't use MySQL on Box 13, so I cannot comment further.
You can monitor HTTP/FTP/Panel functionality with these constantly updated monitors..
