currently in CPanel if one of the sites hits their monthly bandwidth limit, their account goes to limit exceed page. Is there a way to overcome this ? I have some clients where some months they will exceed their limit which is ok for me as a reseller, therefore, I do not want their site to go offline.

One way I can overcome it is manually increase the limit for that month and then take it down. But I am looking for a way where this will happen ?? Any tips....

Thanks

If it's your server, you can log into WHM and tick the "Disable Suspending accounts that exceed their bandwidth limit' box under 'Tweak Settings.'

I am a reseller, can this be done at my level ?

best to talk to your provider and see how to do it and if you cannot ask them to do it for you.

Yes, you can make bandwidth changes in your Reseller(WHM) in "Account Functions" select "limit bandwidth usage"

Sorry I misread your post, Dennis is right.
