No. Although we will set up your hosting account within a few hours at most (absent any billing or payment problems), it sometimes takes approximately 24 to 48 hours for the DNS to resolve to our servers after the DNS information is set. Therefore if your domain is registered elsewhere, you must be sure that when you purchase hosting at Mumbai Hosting, you choose to set the name servers at that time. Otherwise you must login at your own domain registrar and make the DNS/name server changes manually, using name server information we provide after you sign up for hosting here -- the longer you wait to make these changes, the longer until the 24-48 hour wait period begins.
