If this is just an overnight thing i would hang tight for a few days
Last week i added around 40 links to one of my longer tail keywords a few days later i dropped 30 places and bounced back 2 days after that 10 places stronger than i have ever been,
bare in mind this was a test for me and would not normally add that many links in one go but i was testing a theory with the new algo change,
If your page stays down for more than 5 days it could be a problem but i doubt that seeing as your com has jumped back.
