Depends what you're looking for. I don't have too much fine-grained
jitter data, but I have end-to-end ping data taken every ~40 seconds
between 30 hosts over the last two years. More than happy to share
if you'd like it, or want a subset of it. It's kind of voluminous,
but that's what the internet 2 is for. ;-)
(offer extends to everyone, of course).
