From my personal experience of whonix +obfs3 bridges (i use that 1,5 year now) i see that after some time,
days to weeks , depence from where i am connect , will become slow the tor , or even can’t connect at all to a site. There is a simple solution to download new obfs3 and restart tor , then that keeps a lot of days.
So when the slow loading of sites or can’t connect at all take place , that means the bridges got
censored ? and so that means must change them because they stop to hide the fact of using tor?
That is a important question i see.
I am not sure for something , but must keep in mind , i was use for some days the iceweasel browser inside whonix , with disabled proxy settings , also it was installed the adobe flash player plugin on workstation and enabled on iceweasel , this is very bad i learned later , and i never use it from then, so maybe the obfs3 bridges got censored from that ? i don’t know, I say maybe that it was responsible for slow down the loading of sites , i don’t remember if that happens with tbb to, i am not sure .
thank you for reply.
So on latest whonix version i see the support of obfs4 , tor site gives obfs4 so its better from obfs3?
i thing (not so clearly remebmer) i was read on sources from tor site and blog of it that obfs3 are more resistant to censor from obfs4 , litle paradoxial but use in china obfs3 and not obfs4 , why? is new and need more time for become more funcional? That i read before 5-8 months , maybe today the curent level is changed
