If, for example, I have a reseller account and one of my customers overloads server. How do hosting providers act in such situations? Will only this customer or all customers within my reseller package be suspended in this case?

If you suspend a reseller with cPanel I know it suspends all their clients as well. If you suspend just that one site it doesn't effect the whole reseller.

You'll need to ask you [proposed] provider & check there 'terms'.
no 2 providers are the same.
You need to know exactly what your clients want & what your provider offers/limitations are.

Best bet would be to set up reasonable limits & auto suspend if those limits are exceeded.
But that will not help if 'Copyright' or other legalities are broken, you provider has to take action in these cases.

Clearly state what is & what is not allowed etc.

Basically research in depth, what your clients want & who can best provide it.

Ask your provider on their policy. In theory, it could all vary, though most providers (and their customers) would see it as bad business to suspend all end users' accounts due to a single one that causes trouble. A couple such instances and the reseller's business would be ruined.

If a high percentage of your end users turn out to be spammers etc., I guess you could risk having the entire reseller account suspended, as the provider would start to see *you* as a threat (either being a spammer yourself, marketing to spammers, not doing enough checks to weed out the unwanted customers etc).

Yes, I think it is bad too. I am going to start reselling hosting in the nearest future and I am worried about this fact. If one of my future customers start overloading server or breaking company's rule my other customers may suffer as well. Can I suspend such customer myself using WHM to avoid such situation?

Hello

Yes you can suspend or even terminate any customers who are overloading your server, most webhosts will have some sort of fair use policy I would read over your providers fair use policy and if you dont allready have one you should get one drawn up, I would have the cpu/resource usage part of it fairly similar to your providers, being as you have to abide by it too.

Most decent hosts would realise that it is not the account owners fault the server is being overloaded and just suspend the account in question, as they have acess to your whm one would assume. But some hosts may not bother going to the extra effort and suspend the reseller account itself, in which case all accounts under the reseller would be suspended to, untill some sort of agreement is made to remove the offending site/account.

As long as they are under your account yes you can suspend each account individually.

Personally, if you are hosting resellers, I'd always try and contact them; let them know their resource usage is too high and they much bring it down. (Be sure to say in no uncertain terms, otherwise they may not get the message).

Yes thats a good idea, give them a chance before suspending them, perhaps they dont even know they are using a lot of resources.

My experience has been that the host only suspends the offending user and reports to reseller. If reseller doesn't take appropriate action, then further action may be taken against the reseller themselves. But most hosts won't automatically fault the reseller. Not good for business.

This is bang on right here and what I hope the majority of hosts do, but it doesn't hurt to still ask about their policies. So for a reseller I would make sure you check your mail everyday in case of complaints against sites you are hosting on your reseller account. So that could mean whitelisting the hosts domain and things like that. Last thing you need is your account suspended for what you believe is no reason then find out you had several spammers on your reseller account and you never responded back acknowledging you were aware of it.

One reason I could see a host suspending the entire reseller is if they do not pay the bills. But can you blame the provider? Lots of resellers like to do the run away game. So giving free service to all their accounts except their main domain is costing the host money.
