Namecheap has the following policy for expired domains:
The owner of a domain has a non-guaranteed grace period of approximately 27 days after the expiration date to renew the domain at the regular domain rate. If the domain is not renewed, the domain will be deleted from our database and it is transferred to a "redemption period" at the Registry.
If the domain is not re-instated in this phase, then the domain is released to the public by the Registry and becomes available approximately after 80-85 days in the status of redemption or is auctioned off by the Registrar and becomes property of the different party.
The expiration date in Whois changes only in case the domain name is renewed. If it is not renewed the date is left the same till the domain name is released to public.

I'm able to access the site, if you can't, try adding this line to your

I just checked the Comcast DNS servers:
