"cabal update" hangs.  "ping haskell.org" times out.  But haskell.org and hackage webpages are loading just fine.  What's going on?

Lots of servers turn off ICMP packet responses these days

Because users don't really need error messages, that's privileged information for system administrators.

so ping isn't as reliable as it once was for detecting when a server is running.

Looks like haskell.org isn't one of them.

I'm not sure why cabal update would hang.

It takes a while to complete with no visual feedback. Perhaps the network is just slow? Or perhaps the web pages are cached somewhere along the way? -k -- If I haven't seen further, it is by standing in the footprints of giants
