What English-language sites exist covering the European web hosting
and managed services market?

Dear Shore Break, 

I think the best you can use to get information on the web hosting
market in Europe is http://thewhir.com/features/europe.cfm . "European
Web Host Industry Report" section contains coverage of major
developments in the field.

More available resources might be Analysis.com's research products
such as http://www.analysys.com/default.asp?Mode=article&iLeftArticle=868
(for a fee), as well as sites such as http://uk.tophosts.com/ and
www.internetnews.com .

I hope that helped. Please contact me with a clarification if you need
one.
