Our original test was from:

Warsaw
Toronto
Melbourne
Mumbai
Frankfurt
Seattle

So, multiple continents, multiple transit providers.   How many cities / continents would you like?

We can certainly talk to the RIPE Atlas people.

When you redo your testing, I suggest you also test to see where exactly the packet is dropped.  For example, is it dropped at the source, in a transit network or a destination network.   Merely redoing testing against sites which we know are likely blocking extension headers is unlikely to produce different results.

My point is that, given e.g. the results in RFC7872, if you test a 
reduced number of destinations, it's likely to measure "success".

For the numbers to be meaningful to assess whether IPv6 EHs are usable 
on the public Internet, you definitely need to measure against a large 
number of destinations (and also vantage points).

I for one can re-do the RFC7872 experiment -- TBH, I don't expect a lot 
of changes from RFC7872, but... I guess you never now until you measure.

Thanks!
