I am not 100% sure on this one, but I think that Google may have updated it’s PageRank Algorithm. Today I noticed that our site’s PageRank was lowered, so I started to check some other sites. After some digging it seems to be somewhat across the board. Our sites root, http://192.168.15.20:8085, dropped from a PR6 to a PR3. http://192.168.15.20:8085/blog/ dropped from a PR7 to a PR4. http://www.wikipedia.org/ dropped from a PR9 to a PR8. http://www.google.com and https://www.adobe.com/, however, are still PR10.

If anyone else is has noticed a similar PageRank pattern, please post a comment about it.
