#25144: op-us onionperf instance spends much of its time at 100% timeout failure: why? --------------------------------+------------------------------ Reporter: arma | Owner: metrics-team Type: defect | Status: new Priority: Medium | Milestone: Component: Metrics/Statistics | Version: Severity: Normal | Resolution: Keywords: | Actual Points: Parent ID: | Points: Reviewer: | Sponsor: --------------------------------+------------------------------
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: - https://metrics.torproject.org/bridges- 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. -- Ticket URL: <https://trac.torproject.org/projects/tor/ticket/25144#comment:2> Tor Bug Tracker & Wiki <https://trac.torproject.org/> The Tor Project: anonymity online
