Your idea to "Write to Google for a re-inclusion in the index?" may be premature. You need to investigate the problem in more detail first. For example, have you checked to see if you've gotten any messages about a penalty in Webmaster Tools? Also, have you confirmed that these sites were actually de-indexed, or was the loss of traffic due to rankings drops?
From the information you've provided, it would be difficult for anyone to identify the specific cause of the problem.

My sites have not been de-indexed but their rankings have dropped. There is no warning from Google either. I have not made any changes to my website design or installed a SEO plugin. Its just the drop in rankings serving ads from a particular Adsense that concerns me.

Was it really this Monday or was it last Friday? An update occurred last Friday. And if it's this week, are your users American students?

I am not too sure because we have a general drop of traffic on weekends. We have tech and lifestyle blogs a different demographic than students. Any specifics on the update that occurred on Friday?

How many sites are we talking about? Are there other links/similarities between the affected sites besides the adsense account - eg type of content, how that content is updated or sourced.

4 websites. They are of different topics and updated independently and in no way are related to each other except for the Adsense account for serving ads and the server where they are hosted.

Google made an update around the 15th/16th in which they refused to give much detail about but many have noticed. It might not be "network" related but something you do the same on each of the sites that caused the drop. Some questions...
- Images, did you get a good deal of image search traffic? Has that dropped?
- Heavy hitters, did most of your traffic come in on a handful of pages? If so, did any of those lose traffic?
On my site I lost traffic on a handful of pages but gained it on others. Images on those pages that used to be shown up top of serps are now intermittently shown below 12 results for youtube videos. When the image results appear at the top my traffic is good, below... not so much. It's not a sitewide thing in my rather limited data analysis.
