 > '''Log Message Fix'''
 >
 > I'm happy to make a fix to the log message in this ticket, and get it in
 0.2.8.
 >
 > Do you have a suggested "less scary" wording, arma?
 > I'd go with:
 >
 > "[notice] The relay at IP:ORPort has changed its key from A to B. Trying
 a different relay."
 >
 > These messages will only occur on bootstrap, so I think it's ok to leave
 them at notice.
 > But there may be a few if a few fallbacks change keys.
 > And tails users will get then on every boot. Should we reduce them to
 info?
 >
 > Note that this wording and the change of log level will apply even if
 the relay is a guard.
 > Is this what we want? Or should we change it only for the fallback case?
 > (We can do this, there are functions that tell us when we're
 bootstrapping.)
 > If so, I'd say "info" for fallbacks, and "warn" for guards/authorities.

 This is all we need to do to fix this now. I can do it.
