Comment:

 Thanks for reporting.

 Below is the output from recent exitlists for this node. Around
 `2016-03-08-20-04-01` its ExitAddress changes, which roughly corresponds
 with the time of the report here. It took some time but check eventually
 caught up. The exit scanner considers its results valid for up to 48hrs
 and doesn't always rescan at each consensus (notice the times the test was
 performed on the ExitAddress lines).

 There's a detailed answer on stackexchange about false negatives worth
 perusing http://tor.stackexchange.com/a/873
