[afnog] AMS-IX concerns

I finally got the right person at AMS-IX and they've confirmed the chart
reflects erratic traffic from just one peer.  It's non-public though so it
could be JTL, SEACOM, Safaricom, or Google.  We know it's not Google and
probably not SEACOM so that leaves 2 candidates.  My money is on JTL (where
the worst problems have been lately).

Anyway, hopefully it will get fixed.
