--------------------------+---------------------------
 My local wifi is flapping up and down as I try to fix it, and I just got
 this failure from my local Tahoe-LAFS gateway, which is connected to
 exactly one storage server (a !LeastAuthority.com server).

 {{{yu3a}}} is my gateway, {{{66ra}}} is the storage server.

 I get confused about how many levels of "wrapping of remote thing" I'm
 seeing but since there are only two nodes involved, or three if you count
 the introducer, then I guess this means that the storage server told my
 local gateway that it had lost a foolscap connection. Does that make
 sense? Pretty confusing.

 The server was marked as not-connected on the welcome page after this, but
 Foolscap ''did'' eventually reconnect.

 Is this a bug, or should we just close this ticket as not-a-bug?
