Is the .onoin down for Tor users?

Tor onion may be down again? I'm getting:

```
$ keybase login
▶ ERROR unexpected error in Login: API network error: Get http://keybase5wmilwokqirssclfnsqrjdsi7jdir5wy7y7iu3tanwmtp6oid.onion/_/api/1.0/merkle/root.json?c=1&last=22975350&skip_last=1: socks connect tcp 127.0.0.1:9050->keybase5wmilwokqirssclfnsqrjdsi7jdir5wy7y7iu3tanwmtp6oid.onion:80: unknown error host unreachable
```

Start with the reported `keybase login` command and the `.onion` API endpoint in the issue body, then verify whether the endpoint is reachable through the SOCKS proxy at 127.0.0.1:9050. Done would require determining whether the outage is on the onion service or the client connection path and documenting the confirmed cause.
