It can happen that the site is slower than usual when Google and other search engines crawl it all at the same time.

The response time is also a little slower since moved to the new server (three months ago) for European users, since the site is now in Canada instead of France.

Is it normal but the response time of the site is very long at the moment. It seems not to be the case with other sites on my PC so I guess it's IMCDb not functionning well....
