op-us onionperf instance spends much of its time at 100% timeout failure: why?
Now that we've fixed #24996 (moved), we now see on https://metrics.torproject.org/torperf-failures.html?start=2017-11-07&end=2018-02-05&source=op-us&server=onion&filesize=50kb that there's an onionperf instance that spent much of January just totally failing.
What was it trying to do, and was its task actually hard enough to merit such failure?
The op-nl server didn't seem to have this level of difficulty.
op-hk did have problems, but in different weeks than op-us.
The results look similar when I click 'public', so I guess it isn't just the onion destination.
