Comment (by april):

 I just checked and meek-azure works again, for the moment at least.
 Round trip latency of over 3s
 Maximum download speed (one conmection) of 30KB/s
 Opening (hitting enter till results appear) duckduckgo.com takes about
 halve a minute, reddit.com about one minute.

 Connected without bridges over VPN gives me:
 Roundtrip latency of 600ms
 Maximum download speed (one conmection) of 300KB/s
 Opening (hitting enter till results appear) duckduckgo.com takes about 7
 seconds, reddit.com about 15 seconds.

 Any obfs4 from bridges.torproject.org don't connect directly.

 There is a very notable gap in speed between meek and VPN+Tor. I can do my
 regular stuff (reading, buffered low quality videos, GB sized downloads
 for system updates) over the later.
 Over meek videos are not feasible, System updates take days instead of
 hours, and the latency locks me out of everything using Google Recaptcha.
 Reading is still possible, but it is annoying to wait at least a minute
 for a page to load. Especially when searching for information.

 This makes it difficult for me to provide cover traffic, strengthening the
 anonymity set.

 But as long as meek-azure connects, I can access about:config of Firefox
 to use Orbot instead. Therefore my ticket is solved. Still there are
 legitimate reasons to connect to external Tor processes. It would be nice
 to not intentionally be barred from doing so.
