@edsu: Could you run the command with verbose debug output please? (somewhere between ssh -v and ssh -vvv)
Thanks for the quick response! Here you go:

Hmm, looking at the docs perhaps it's no longer possible to ssh to bastion.wmflabs.org and then ssh on to ws-web? Should I follow the instructions at this page to set up bast1002.wikimedia.org as a proxy?
Bast1002 is a bastion for accessing hosts inside the production network at Wikimedia rather than virtual instances in Cloud VPS. The bastion-eqiad1-01.bastion.eqiad.wmflabs (also known as bastion.wmflabs.org) is the correct bastion to use to access instances in the wikistream Cloud VPS project.
I will poke around in the log files on ws-web.wikistream.eqiad.wmflabs to see if I can find a reason for the auth failure.

Not super helpful logging. I did see some logging in a vaguely similar time period about nslcd reloading. That service brokers lookups of your ssh public key in LDAP among other things. It is possible that you just had really bad luck and the
instance was unable to talk with the LDAP server at the time you tried to ssh in.
@edsu Could you try logging in again? It would be helpful to have a ssh -vvv output if you are still not able to connect successfully. At that level of debug output hopefully we will be able to see the the fingerprint(s) of the ssh public keys that your ssh-agent is offering so we can check them against the keys you have authorized through wikitech/toolsadmin to access your account. If that still doesn't get us anywhere we may have to sync up for live debugging on the #wikimedia-cloud Freenode IRC channel where I watch the logs in various places as you try additional logins.
Trying to be helpful while we work on the ssh issue, I believe I have gotten the wikistream service back up and running for the moment.

The /etc/init/wikistream.conf upstart process really needs to be converted to a systemd unit to make this easier. Some docs on https://wikitech.wikimedia.org/wiki/Nova_Resource:Wikistream about how to restart both varnish and the node process would be extra nice.
I created task for this and added it to the documentation workboard: https://phabricator.wikimedia.org/T232547
Thanks for getting wikistream back working again. I'm still unable to ssh in however.

It appears that you are doing an ssh from your personal computer to bastion.wmflabs.org, and then from the shell on bastion.wmflabs.org trying to ssh to ws-web.wikistream.eqiad.wmflabs. This would only work if you are using ssh agent forwarding so that the ssh keys on your personal computer are available to the ssh process on bastion.wmflabs.org or you have ssh private keys stored in $HOME/.ssh/ on bastion.wmflabs.org. Based on the -vvv output you gave I believe neither is the case. That's actually not horrible as neither practice would be ideal. Agent forwarding has a potential to expose your ssh agent to root users on the intermediate host or worse to anyone who finds a local root exploit on those same hosts. Storing ssh private keys on any Cloud VPS instance, whether it is a bastion or not, is not a great idea either for the same reason of potential exposure of the private key to anyone with authorized or unauthorized root access to the filesystem.
The "best practice" method of accessing instances via ssh is by using the bastions as a "jump host" rather than with an ssh-in-ssh session. https://wikitech.wikimedia.org/wiki/Help:Access#Accessing_instances_with_ProxyJump_ssh_option_(recommended) documents the easiest way to set this up if you have a modern openssh client. There are also instructions there for older openssh clients which implement the ProxyCommand directive but not the ProxyJump directive. If you are using PuTTY on windows, see https://wikitech.wikimedia.org/wiki/Help:Access_to_Cloud_VPS_instances_with_PuTTY_and_WinSCP#How_to_set_up_PuTTY_for_proxying_through_bastion.wmflabs.org_to_your_instance
@bd808 thank you! I only was doing the ssh-within-ssh because it worked for me in the past. But I've got ProxyJump working fine now, and can access ws-web, so I appreciate you taking the time to explain this solution.
I'm sorry to have to reopen this. But I've been notified that wikistream.wmflabs.org is down again and I no longer seem to ssh with the the ProxyJump configuration? Here's the log of my ssh attempt:
