I don't know what's happening with hackage, but if you're using stack in your workflow a simple workaround is to build docs locally and search them with a shell script. For example:

$ stack haddock async

And then muck around in .stack-work or ~/.stack. I've written a bash/fish script to do the search for you here: plredmond.github.io/posts/search-haddocks-offline.html

Docs not being built can be quite frustrating; for those dark times I
build them locally:

Living with a flaky WiFi, saves me from screaming at the monitor quite
some times.
