We also ran /afs/slac/package/pinger/write_offsitenodes.pl to generate /afs/slac.stanford.edu/package/pinger/pinger2/share/pinger/pinger.xml file for the SLAC MA. This works.
For the IPv6.google.com raw data from pinger.pl only reports min/avg/max RTTs, there are no sequence number or associated RTTs. This has to do with truncating the ping/icmp MTU between SLAC and ipv6.google.com and no RTT being reported for each of the pings. On the other hand pings are not truncated between SLAC and perfsonar-lt.cern.ch (2001:1458:301:a7bc::100:15) and many other IPv6 nodes .See below for examples. I was just unlucky in the host I chose to test against.

Thus I added perfsonar-lt.cern.ch to NODEDETAILS. and got:
