We would recommend upgrading your hosting account at IFastNet Premium hosting accounts , premium hosting accounts have MUCH higher resources dedicated to them.
Other Information
I am very aware that my bandwidth and any other limit on my account has not ever been passed, i uploaded an image to let you see. I would really need something to understand where I can take track of this resource and why actually it is none of those listed on the account cpanel page.
The Account Statistics page has more graphs on the resource usage of your account.
But the numbers are intentionally vague. We want you to stay within the limits and upgrade if you need more, not try to skirt it and use as much power as possible for free.
