Shortlinks appear to be 3 character (lowercase + digits), appears to be sequential (judging from patterns in sequential shorturls). Valid returns 302 with destination in Location header, invalid returns 200 with error page. GET and HEAD (as of 01:39, 2016-05-15 (EDT)). Alive requires account to use Rechecked 2016-07-20. Rerun from 0 finishing on 2023-07-20 with 45 more urls discovered from the last time it was run. Lowest Sequence number was 4245 that resolved successfully and ran up to Lowest Sequence number 343600. Investigation needs to be done on random short links giving 502s consistently. Perhaps broken?
