You'll probably have to manually make the changes to each link (load it up, let it 404, and then change the www to web2), since the www.flyertalk.com maps to either web1.flyertalk.com or web2.flyertalk.com depending on server load.

When an issue happens, it's usually web1.flyertalk.com that has "failed", which is why web2.flyertalk.com generally seems to keep working (though at a reduced level).
