#WhatsMissing: A tool to check if #TorBridges are still available/online/reachable that one can use either #standalone (with #TorBrowser and/or #Tor Expert Bundle) or on @tails_live / @tails / #Tails.

• Cuz I do run into issues and kinda want to sort #Bridges by availability so I don't waste time on a #TorBridge that is down and also thin-out the list of bridges that ain't online anymore.

Whilst I do acknowledge that @torproject do disrecommend having a huge list of Tor Bridges on hand, I do regularly need them for contacts who are behind a #GreatFirewall and can't #SSH-Tunnel out of it.

• Sadly #BridgeDB doesn't offer good #filtering options so one can't just query types effectively like "I need #webtunnel on #IPv4" or "I can only use Ports 80 & 443 on #IPv6" which may work.

Espechally being able to filter for #IPv4only and not just #IPv6only is something I miss, alongside the filter for #PluggableTransports type as @guardianproject #Orbot seems to only handle #obfs4 and not webtunnel or #meek at all...

• I'm pretty certain that merely pinging a bridge at it's port isn't working as a shure-fire way to check for it's availability.

On this #GivingTuesday, we are launching 10 public @torproject #obfs4 bridges!

We don't expect these bridges to be particularly good at evading #government #censorship since they are in the same IPv4 /24 subnet as our exit relays. Countries like China and Russia undoubtably already block our subnet. However, we think they are a trustworthy (and fast) guard node when configured.

If you'd like to try one of our bridges, we have published them here:
