Comment (by cypherpunks):
op-us is on a streak of timeouts again that started on April 19, 2018
through the latest data point, a running total of 21 days and going.
https://metrics.torproject.org/torperf-
failures.html?start=2018-04-12&end=2018-05-12&source=op-
us&server=public&filesize=50kb
op-hk and op-nl are experiencing spikes at the same time but not
constantly like op-us is.
Days before that started, the number of bridges fell quickly on April 15
and 16:

ipv6.html?start=2018-04-12&end=2018-04-19
-
https://metrics.torproject.org/networksize.html?start=2018-04-01&end=2018-05-01
The loss of bridges might be explained by Google and Amazon stopping
domain fronting on April 13 (#25804) and announcing it the week of April
23 (https://signal.org/blog/looking-back-on-the-front/ ) respectively.
The working idea is that their decision is a result of a Russian court
banning Telegram messenger on April 13 and the collateral damage from the
ensuing cat-and-mouse game between Telegram servers and Roskomnadzor, the
Russian internet censorship body, blocking IP subnets.
However, the sudden loss of bridges might not be related to the timeouts
of op-us starting April 19. The wiki:doc/MetricsTimeline hasn't been
updated with clues either.
According to #21653 and wiki:org/operations/services/onionperf, op-us is
in Washington, DC at https://op-us.onionperf.torproject.net/ and
https://199.119.112.144, Allied Telecom Group, LLC, Radio Free Asia, not
at Google, Amazon, or Azure.
