today i try to register domain. whois says its available, checkpagerank.net shows available, godaddy shows unavailable. alos namecheap shows unavailable, and when check the whois, it says domain still available can be register. but cant register it either. why?
Two possibilities - someone just registered it, or its in the process of being deleted. When someone registers a domain, it can take up to two days to appear in WHOIS. When a domain deletes, it dissapears from the whois registry for 5 days before its available again.
