Today at 18:10 UTC I turned off the CDN endpoint formerly used by meek-amazon. Tor Browser switched away from this endpoint 7 months ago (https://bugs.torproject.org/21918), but Orbot only recently switched. Just before I turned it off, the endpoint was still being heavily used, so it's possible that some users will have been suddenly disconnected. == How to fix == Users should upgrade their Tor Browser or Orbot. Tor Browser 7.0.8 Orbot 15.5 Users can use meek-azure if they need connectivity in order to upgrade. == Technical information == d2zfqthxsdq309.cloudfront.net is the old, deactivated endpoint. d2cly7j4zqgua7.cloudfront.net is the current endpoint. If a user has a custom bridge line that looks like: meek 0.0.2.0:2 B9E7141C594AF25699E0079C1F0146F409495296 url=https://d2zfqthxsdq309.cloudfront.net/ front=a0.awsstatic.com they need to change it to: meek 0.0.2.0:2 B9E7141C594AF25699E0079C1F0146F409495296 url=https://d2cly7j4zqgua7.cloudfront.net/ front=a0.awsstatic.com Most users will not be using custom bridge lines like this and only need to upgrade.
