[GTER] BCP38 deployment in Brazil

[Matthew Luckie]

Hi,

I am wondering if you can help me understand why it is that Brazil, as
a country, seems to be active in deploying BCP38.  When I look at the
monthly reports that CAIDA's Spoofer Project sends to GTER, there are
often 5-6 networks that have deployed BCP38 in the past month.  This
is more than in other countries / regions.

e.g.:

https://eng.registro.br/pipermail/gter/2019-April/076517.html
https://eng.registro.br/pipermail/gter/2019-March/076311.html
https://eng.registro.br/pipermail/gter/2019-February/076145.html
https://eng.registro.br/pipermail/gter/2019-January/075927.html
https://eng.registro.br/pipermail/gter/2018-December/075773.html
https://eng.registro.br/pipermail/gter/2018-November/075593.html
https://eng.registro.br/pipermail/gter/2018-October/075356.html

You can also see the effect in https://spoofer.caida.org/remedy.php
where 112 of the 526 (21%) of the inferred remediations were in
Brazil.

Is the Internet Society's MANRS effort having an effect, or is
something else local in Brazil encouraging deployment of BCP38?

Thanks,

Matthew
