Being a Web Developer for 5 years I have done a lot of running to find out a suitable webhosting partner. Right from WebSuvidha, Yahoo, Net4 to Znet. Easilly Znet India is the best among the most other hosting service providers in India. Cost Wise they are ok. The Domains are little costly but you can always purchase domains with India Links or Go Daddy and then purchase the space with Znet.
The best thing about Znet is the server speed. Usually the website loads very fast. Net4 also has good speed but they do not provide cpanel and we have to pay extra for database and email and sub domains. So from many perspective znet stands out as the best webhosting service provider. Particularly their customer support is Very Good and its very timely.
Only one negative thing that I encountered with Znet was they changed the IP Address and didnt take up the database back up correctly.. What they restored later didnt have data entered for 2 hours. But they were prompt in reply and apologized for inconvenience and also provided their latest back ups. Except for this incident, I have only positive things to write about Znet. Atlast I have found a decent web hosting service provider
