- Company with a reliable track record (profitable and/or tested by time)
- Fast connectivity
- SSD drives
- Knowledgeable in-house true 24/7 support
- Preferably continuous data protection (off-site)
- Choice of panel software (not a deal breaker, however)
- Friendly attitude
I will look for support and enough space. If everything is good but support is not fast , you may loose your customers. so before going for reseller hosting, make sure that support staff response is fast.
SSD Based Servers
Full Hosting Data Access
PRIVATE Name Servers
Third Party script support
Dedicated account manager
24/7 Ticket and Live chat support
Website/Software Maintenance support
Above features allow me to concentrate on sales instead of concentrating on technical issues
Below is the main things I will suggest you to check
1. Infrastructure is the main thing you should look.
Whether they are having SSD drives or not
Details of the Data center where the server's are located , Whether the DC is providing cheap quality products etc
Details of the Software Running in the Reseller Servers like Litespeed, Nginx Reverse Proxy, Mysql on Seperate SSD drive, Mysql versios etc
Whether they are having any Raid like Raid 10 or raid 1 etc
Spec of the Reseller Servers to confirm it is having latest CPU and enough memory etc
Great Network Support and possibily IPV6 support as well now a days
2. Second most important thing is Support.
Make sure the support is having 24/7 real support and check and confirm the response timing for the below and see if they are meeting the SLA
24/7 Inhouse Monitoring of the Services and if possible to have some custom checks url site check for re-sellers for their main site.
3. Third important thing I will say is Proper Backups for the data
See and confirm the backups are continuously monitored and backups are not in the server itself. So that you can get the account's backup even if the server is badly damaged.
Another thing you need to consider is you should get the hosting from the location where most of the targeted visitors will be for get hosting from a company having US data center if your targeted visitors are from US.
