Comment (by phw):

 I'm making a pass over our list of default bridges and noticed that none
 of our FTE bridges are working.
 128.105.214.162:8080 and 128.105.214.163:8080 seem offline. My Tor Browser
 says:
 {{{
 4/9/19, 19:13:36.424 [WARN] Proxy Client: unable to connect to
 128.105.214.163:8080 ("TTL expired")
 4/9/19, 19:13:36.425 [WARN] Proxy Client: unable to connect to
 128.105.214.162:8080 ("TTL expired")
 }}}

 131.252.210.150:8080 is reachable over TCP but I'm unable to use it as FTE
 bridge. My Tor Browser says:
 {{{

 Kevin, do you know what's going on here?
