Verisign, the company responsible for running the .com and .net domain name systems announced today that they have implemented "rapid updates" for the .com and .net domain names. This means that from now on, you won't have to wait for days before your new domain name is fully functional or your domain name resolves to your new location after changing web hosts. Details

This looks like the same update speed .info and .biz domain owners have benefited from since they (.info/.biz) went live nearly 3 years ago.

On the free .info domain front, I can report that Dotster have joined the wave and offers up to 25 free .info domains to anyone. Details. Update: are also offering the same deal.
