DNS cache update history

Worth tracking more closely perhaps

Okay, I'm currently faced with the third dns change for one of my sites in the space of 2 months. So far I've been pretty lucky with Google picking up the latest version of my site but as ever I am a bit nervous.

I have been investigating and the is evidence to suggest an update of the cache around the time of deep crawling in January and February (in fact I can also confirm the February one)

Is there anyone out there who changed dns after February 5th and is now having the new version crawled to indicate a March update of the cache?

Also does anyone know if Google will check for dns changes if it encounters a dns related error when crawling? I've noticed some sporadic reports of people having new sites picked up within days whilst others are waiting weeks. I am wondering if maybe taking the old site offline completely after a few days is the best option - which goes against the opinions of most, including myself till I just thought of it! (Not that I will have a choice as I suspect my host will switch off the old server pretty quickly anyway)

Olias,

I switched ip on Feb 13. I am being crawled by the freshbot as well as deepbot.. Not sure if it proves anything. I ask for the hosting service to keep it up on the other server for a while. Not sure if they did. I can't get on the old server anymore. But I think google found me without any trouble. Hope it helps you out.

To check if the site is still up on the old server, make an entry for your domain in your hosts file, with the old ip. This will temporarily point your domain at the old server
