Hello,
This is Carlos from LACNIC. We are seeing the same poor RPKI data
quality in our region and we share the same concerns that Alex has
expressed.
Currently our hosted system *does not* renew anything automatically. It
will send automatic reminders when expiration times are near, but that's
just about it. ROA upkeep is left to the users.
The system does not prevent users from creating ROAs with expiry times
100 years in the future, although no one seems to ever change the
default value of two years.
The most common operational mistake we are seeing has to do with failure
to create covering ROAs for BGP downstream customers while having too
long maxLen values in the upstream ROAs.
While I have personally contacted some of our members regarding the bad
ROAs, we have so far met with limited success.
Warm regards
Carlos

Hi,
No sooner have we washed our laundry after returning from Vienna, then
it is time to start thinking about what we're going to talk about in
Ljubljana towards the end of April. Or so it feels like anyway. That
could just be age on my part.
We are scheduled to meet after lunch on Wednesday, April 18th. If you
would like to suggest any content, please email either myself, Joao, or
even both of us through <routing-wg-chairs(a)ripe.net>.
All the very best,
Rob
