Redirect in case of unresponsiveness

[erlend-sh]

If a personal weird-page stalls for more than 3.5 seconds, we should redirect the visitor to the Backup Redirect, if one is set.

My personal Backup Redirect would be set to https://github.com/erlend-sh

Just to do the smart redirect we would have to have some proxy service running highly available in front of Weird anyway, so what I'm thinking is that we can build this into the same service we were thinking of having that would just serve the pages from cache, even if the main site is not available.

Squid, a very common reverse proxy can do this natively, so it is probably just a matter of us deploying squid or maybe a more cloud native caching proxy like it.
