Everyone keeps speculating that normal fluctuations are Panda.
You'll know when Panda hits because it will start PANDEMONIUM in the SERPs.
To check for Panda, simply find results that got hit hard in google.com and keep comparing that to your country's results. When you see google.com, .co.uk, .ca, .fr, .de, etc. all showing results similar to the Panda version of google.com results, you'll know you've been PANDOMIZED.
Until then... fluctuations as usual best I can tell
