Comment (by karsten):

 Alright, I just looked at the latest database file from yesterday
 (GeoIPASNum2.zip, shasum 997932353f5824eeb760459e0ad5f8ff2226c01c), and I
 believe we should update to this one rather than keeping the May 23, 2016
 file.  Some numbers:

 ||'''Database'''         || '''AS number and name'''|| '''AS number
 only'''||
 ||February 24, 2015      ||                  213,789||
 318||
 ||January 4, 2016        ||                  235,323||
 514||
 ||February 1, 2016       ||                  236,474||
 544||
 ||'''May 23, 2016'''     ||            '''242,462'''||
 '''2,043'''||
 ||June 6, 2016           ||                  187,415||
 57,773||
 ||June 13, 2016          ||                  188,139||
 57,179||
 ||July 18, 2016          ||                  245,367||
 1,362||
 ||October 9, 2016        ||                  250,573||
 1,372||
 ||'''December 3, 2016''' ||            '''250,447'''||
 '''1,010'''||

 I also compared AS number/names to a much older database from February 24,
 2015 that I found somewhere else on my hard disk.  My idea was that
 organization names don't change that often.  I attached a graph showing
 how newer databases compared to that old one.  It looks like if we're
 roughly back to normal again.

 [[Image(same-number-name-as-2015-02-24.png, 600px)]]

 And this new file apparently doesn't have the issues stated above with
 AS8620 or AS12876.

 So, let me ask: are there important reasons '''not''' to switch to the
 December 3, 2016 database?  If I don't hear major concerns by, Thursday,
 I'll bring this up at the next metrics team meeting and ideally decide to
 switch.
