Google has at least one datacentre with VERY OLD data in it.

I know of a site that had both www and non-www pages listed. Many were without title and description. Some pages were duplicated (under both www and non-www) in the SERPs and other pages were completely missing.

In March a 301 redirect was set up, and gradually the listings corrected themselves. As of a few weeks ago, about 120 non-www pages were all listed with proper title and description, and all the www pages were no longer listed.

However, I have found that on a different datacentre there are now 92 www pages listed as supplemental results, and the listings for the non-www pages are are messed up too. The cache dates are all from December 2004 and January 2005 on this datacentre.

In regular google.com results the cache date for this site is only several weeks to a month old for all pages.

.

For some other search term (actually an email address that has been removed from many sites) I also see the "old" datacentre bringing up 15 sites as showing the email address, but those are results with a cache date from January 2005 again.

In normal google.com results there is only one match for the search query, and with a recent cache again.

The IP for the "old" results is [216.239.37.99...] and there are several others too. These "old" results have been around for many weeks now.

I see [66.102.9.104...] as having the "new" results on it at the moment.
