I have solved two issues on my blog:

• The visitors log part didn’t work correctly during the last days, and was massively slowing down the load of the blog’s homepage. This issue didn’t impact the RSS feed. This service is based on gVisit and feed2JS.
• I couldn’t publish my entire blog anymore on blogger, no idea why, excepted that the publishing of the whole blog takes now some time :-) About 20 minutes at least. It is also solved and the index and archives are again available properly.

Sorry for the inconvenience!
