Moving Servers

Affecting AdSense, News, Google?

Just started planning the move from a shared environment to my own server.

After a while I though that I should have both servers running with the same backend SQL Server. Why? Because when serving a page on the new IP, if the AdSense bot is still looking on the old IP it would get a 404 for the new content, thus giving me either some site-targeted ads, or (worst) PSA/defaults.

Any comments on this? Have in mind this would be seen by the bot as a single server, since it will only resolve to one of the IP addresses - hopefully to the new one ASAP.

Also worried because of news.google.com. Same case - in general any news item posted in my site shows up on news.google.com after 15 minutes or so. I don't want to miss this traffic...

Comments?

Keep both running until you see search engine spiders on your new machine (as they become aware of the new IP).

Changing IP's is always a risky business. The major search engines are updating IP information much faster than they use to. I have noticed that some smaller companies are still caching DNS data for 30 days or more before updating it. In my view, these search engines are not worth paying attention to, because it won't be long until they are history!

yes, let the old httpd server running and serving your pages for some time and watch the logs of both servers to see when most users and bots have learnt about your new IP address.

However, contrary to conveniently running the old httpd in parallel, be sure that you don't do this for your DNS zones: scratch your old DNS zones immediately to not suffer from bizarre long lasting DNS cacheing effects.

Nice, thanks all!
