#9765: TorDNSel exit lists are missing expected data

 Priority:  major            |      Milestone:

-----------------------------+------------------------
 I've run some checks on the exit lists that we're using for TorCheck,
 here's some stats I'm seeing a recent file:
 Missing: 629 /* IPs not in the exit list */
 Same: 463 /* IP in exit list matches IP in consensus */
 OK(Updated): 19 /* IP from TorDNSel was helpful! */
 Total: 1111 /* Total count of IPs in the current consensus */

 This is from comparing routers listed in the exit lists and comparing the
 fingerprints to that listed in teh consensus. There's 2196 lines in the
 latest exit list (ignoring header lines) which means the exit list has 549
 routers listed (with some not in active consensus). This is a far cry from
 the 1111 listed in the consensus.

 So the problem is, we're having to use 629 self published IPs (from the
 latest consensus doc) which aren't always accurate as you know. This is a
 pretty problem for a project like TorCheck.

 For reference, the exit list I'm referencing is 'Downloaded 2013-09-18
 03:02:02', but this has been a problem since I first saw it a week or so
 ago. (We assumed it was intermittent at the time)

 Can you investigate why TorDNSel is missing so many IPs? If you're not the
 right guy/gal, please pass this back and I'll find a new owner!
