Comment (by atagar):

 I find the 'fast' comment amusing. I first reported that a relay was
 publishing malformed extrainfo descriptors over three months ago so...
 yeah. 'Fast' isn't the word that comes to mind. :P

 Directory authorities should not publish malformed documents. This is a
 gap in the validation tor does. This is why I have a DocTor check that
 validates everything coming from the DirAuths - because Tor's validation
 is quite a bit laxer than Stem's.

 > How many relays does this affect?

 At the moment one. A single relay has been publishing malformed ExtraInfo
 documents for months.
