Just over a month ago I moved servers for one of my websites, which changed the IP address. However, this server wasn't quite what I need so I will need to change again in the next day or two - changing the IP address again.

I'm familiar with moving sites around and wouldn't have any downtime or DNS resolution problems during the move (i.e, active on old IP for a while).

My question is... are there any known problems with search engine traffic when changing the IP address too often? My site is quite large and an authority site, but I didn't know if changing the IP twice within a month would trigger something.

I understand that the conventional logic is that there is no penalty for changing IP (assuming it's done properly), however I've read tales of some people suffering when making a similar change. I guess they may not have done the move properly, but I wouldn't know.

Any thoughts on this would be very welcome.
