for features like advanced censorship circumvention or onion services
is not exactly straight forward on mobile operating systems, because
they tend to be way more locked down than traditional computers.
Currently, we can successfully test pluggable transports in 'managed'
mode on old versions of Android. However this technique will likely not
work on the latest version of Android and never worked iOS to begin
with. We have shared our findings with the Arti developer team and hope
they’ll work on getting us to full Pluggable Transports support,
integraing with our existing IPtProxy Library soon."</span></li></ul></div><div><ul><li><span>Unofficial(?)

collect what we want them to. I can run prometheus locally but am unsure
how to match this with a realistic onbasca test that can actually show
whether the metrics are useful/correct. Is there a known way to do such
tests other than deploy and find out?</span></li></ul></div><div><br></div><div><span>Itchy Onion: 202</span><span>3</span><span>-</span><span>0</span><span>5</span><span>-</span><span>04</span></div><div><span> Last week:</span></div><div><ul><li><span>- </span><span>Costa Rica</span></li></ul></div><div><span> This week:</span></div><div><span> - </span><span><a href="https://gitlab.torproject.org/tpo/anti-censorship/team/-/issues/112" rel="noreferrer noopener">https://gitlab.torproject.org/tpo/anti-censorship/team/-/issues/112</a></span><span> (Some bridges are reported offline but are online and working)</span></div><div><ul><li><span>-
