Dear colleagues,
How does the largest cloud provider worldwide perform
Traffic-Engineering? What are the implications for the geo-distributed
applications running in the cloud?
Marco Chiesa and his colleagues explored these and more questions
through a comprehensive set of measurements across the Amazon Web
Services (AWS) cloud network.
Please find the results on RIPE Labs:

Marco will be a RACI fellow at RIPE 79 and will present his research there.
Kind regards,

Hello!
My colleagues and I at the University of Tennessee recently completed a
study on the “Peerlock” route leak protection system (
https://archive.nanog.org/sites/default/files/Snijders_Everyday_Practical_B…)
and related defensive filtering techniques. Specifically, we probed for
evidence of these systems on the control plane and attempted to locate
filtering sites. Additionally, we evaluated the system's effectiveness in
simulation.
The pre-print of this paper is available at:
https://arxiv.org/abs/2006.06576. While this work was previously mentioned
here by Job Snijders, we want to make an additional push for comments from
network operators. Our experimental design and findings in Section 3 may be
of some interest.
Most importantly, if any of the Tier 1 networks could confirm or challenge
our findings with respect to their filter placement, that would be
enormously helpful! We realize that this information is often secret/under
NDA, but providing some element of ground truth would assist us in
correctly evaluating our work.
Thank you!

Hello,
For the every IPv4/v6 network I'm checking, RIPE Stat gives me
"announced": false
result.
I'm observing this since last hour or two.
Is this the outage or output format change in the RIPE Stat?
Thank you.
