I have my domain BQQKSHELF.COM that I bought through Dreamhost. I set up a CNAME so that zach.bqqkshelf.com points to my app at zach.heroku.com.
The app at Heroku is working fine. Everyone can agree on that.
When I go to zach.bqqkshelf.com, everything seems to work okay too. When I ask my roommate to go to it, it works. When I go to it on my iTouch, it works.
When I IM my friends and ask them to go to zach.bqqkshelf.com, they get a time out error.
How is this possible?
It sounds like you might have a caching issue. Did you have a previous value for zach.bqqkshelf.com? (I.E., did it used to point somewhere else?)
It can sometimes take a while (at least a day) for DNS changes to propagate, due to the distributed and highly cached nature of DNS.
Just in case you're curious, this is almost certainly a problem that your friend on IM is behind a Micrsoft Server 2003 DNS server; I've tracked down the Dreamhost + CNAME issue to that on our end.
When I ping zach.bqqkshelf.com, I get:
PING heroku.com (75.101.145.87): 56 data bytes

I've flushed my DNS settings on Dreamhost, I'll see if that helps. In the meantime, is there a way to test without IMing my friends?
Also, where would this hosts file be?
