(I sent this already in reply to another thread but with too narrow topic, and i think
it's important enough to deserve its own. So pls excuse if you already read this.)
--------
To make the redirect a javascript is not a good idea. At least 2,213,922 users will never
see it
https://addons.mozilla.org/en-US/firefox/addon/noscript/?src=search
and maybe way, way more since there are many similar features on any browser or platform.
Today, virtually NONE of my (many) friends ever noticed something changed, until i told
them.
And even with js, you can see the 'real' page popping up first before the redirect
takes action. It does not feel like 'oops wikipedia is gone !!?' but more like
just another anyyoing advert.
You should do a straightforward real shutdown instead, and deliver a fake 404 with
explanation link.
And for several more days.
And yes i would even block editing since this is also alerting people.
