To make the redirect a javascript is not a good idea.
+100
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.

Doing it via 404s would mess up search engines.

Do it via 503's then.
Cache pollution.

It would have to be a severely broken cache to be polluted by a 503. 503 is for temporary unavailability, you would be stupid to cache it.

You do realize that going by what you are saying. If 503's weren't cached for that reason, then EVERY single request would be forwarded to the apaches. That means all the cache optimization would disappear and ALL of Wikipedia's IMMENSE anonymous user traffic that's been sustained by the caches would suddenly start all hitting the apaches. Naturally the cluster is not designed to handle that. In fact I bet it could take down the blackout page by essentially DoSing Wikipedia.

I'm talking about external caches, as I assumed everyone else was. The internal caches are entirely under the WMF's control so they can be made to do whatever the WMF wants them to do. There's no problem there.

The operations team can indeed do "whatever they want", however they do not have infinite amount of time to determine how to do it and test it

I suppose the 503 could be provided by the squids for en.wikipedia urls, instead of by the origin servers. That probably also means starting with an empty enwiki squid cache after the blackout.
