Caching and Nginx are your first friends, every time.

The registration website crashed in time for the last day of "Early Bird Registration"
Yes, the centralnotice yesterday killed the site and was took down.
I am really disappointed by this. It should be obvious to everyone that a single server cannot cope with a centralnotice on Wikimedia projects, served by 300+ servers.
I have this discussions almost every month. Once WMIN is abusing the server, another time WLM, this time Wikimania. Each and every time nobody even thought a second to at least notify the sponsor of the server before doing something like this.
And I say this again and again every time, to no avail.
The problem can be avoided so easily - using a static HTML landing page (even PHP should work, just avoid any database transactions on the landing page) and talk before you do something. I was away for a few days (Jury meeting in London, weekend) and did not use a computer for two days, hence I could not see or react to anything. If I knew, I would've giving some hints beforehand and made sure I am monitoring the situation closely during that time.
