Page Rank fluctuate?

Recently I have noticed the page rank of my sites fluctuating and wondered why this was.

Rumour has is that Google changed its algorithm recently, different Google data centres hold a different rank for your site.

Depending on the data centre serving you at the time, your page rank will fluctuate. As the rank is consolidated across data centres so it will stabilise.

PR drop shouldn't be a big worry unless it affect your ranking.
