Is this a Namecheap specific issue or more general to eNom who they are a reseller for. Nothing on the enom system status page... http://www.enom.com/registrynews.asp
Enom is definitely having issues getting whois data, although I was under the impression that Namecheap was now accredited and as such would have started communicating directly with the registry for .com and .net at least. Maybe not though.
They can be accredited and still resell, which I think they may be doing for some TLDs. For each TLD you want to be a registrar for you have to go through some sort of accreditation process with that TLD, so getting direct access to a large list of TLDs is quite a significant effort. It may just be that they haven't gotten to it yet for all of them.
Domain names in the .com and .net domains can now be registered
with many different competing registrars. Go to http://www.internic.net
for detailed information.
