MSNBot increasing activity

MSNBot seem to have increased its activity over the last week or so.

Having viewed the stats for several of my customers recently I've noticed that MSNBot has recently increased its activity dramatically. In some cases creating as many or more hits than Googlebot.

Although on some sites it's only made a small amount of visits however most of these are static sites and have not been updated much.

Has anyone else noticed this activity?

Yes, msn bot is visiting the sites and doing the deep crawl. I think msn is in the process of building the database.
