Same tests from RIPE Atlas pings towards
nl-ams-as3333.anchors.atlas.ripe.net today:
48 byte ping: 42 out of 3406 vantage points fail (1.0%)
1473 byte ping: 180 out of 3540 vantage points fail (5.1%)
Of the 180 vantage points that failed for the 1473 byte ping, 142 were
successful in receiving at least 1 reply for the 48 byte ping.
Measurement IDs in RIPE Atlas are 1019675 and 1019676.
