I still don't know what's going on. I'd say any of these are possibilities:
- The bug that results in fallback directories getting extra DirPort traffic
(23862)
- DDoS
- HSDir activity (the node in question did have the HSDir flag before being
knocked offline)
- A connection limit upstream

I'm not sure. I know I haven't had this problem until recently. This node has
been around on the same provider at the same IP for 700+ days. So I'm leaning
away from this being a provider-level issue, but I don't really have the data
to back that up. Any suggestions as to how I could make this determination?
More broadly, any tips for troubleshooting this beyond looking in the Tor logs
and syslog would be appreciated.
> There's 0.2.9 nightly, but I don't know if we have an 0.2.9-release build.
Yeah, unfortunately I could not find a 0.2.9.12 dpkg. I did find a deb, but it
wouldn't install due to mismatched dependencies. I was able to get 0.2.9.12
installed from source, and briefly had it running, but it didn't have a service
wrapper, and generally doesn't jive with my normal practices and Ansible
scripts and such. So I bailed on that and am running the latest 0.3.1.7 package
from the torproject repo again.
It's a shame there's no Ubuntu package for the long-term support Tor release.
Thanks Teor for filing a ticket, but it doesn't look like it will be acted
upon. It seems like a problem to me. I guess it's a matter of what is
considered "stable"? Seems like the package maintainer thinks 0.3.1.7 is
stable, while you (Teor) think it's not? I'm stuck with it for now.
I've scaled both of my fallback nodes up a bit (more CPU and RAM), and things
seem stable at the moment. We'll see what happens. I'll take note of when the
HSDir flag comes back.
Thanks for everyone's help.
