Dear Baldur,

Lets say someone makes an announcement that creates a RPKI invalid and
it is determined to be a mistake. They then go back and add ROA
objects to fix the problem. With this reactive RPKI approach then
continue to block the route because filters where already generated
and pushed out to routers? Or in other words, if the system can insert
the filter in less than 60 seconds, how long does it take to get rid
of the filter again when someone publish valid a ROA ?

What you describe here is what I'd call a "Garbage Collection" process.
Garbage collection has to happen periodically.

Probably not slower than once an hour. See the following link for an
attempt to document that type of aspect of RPKI ROV deployments:

Maybe HE can comment on their current timers?

Kind regards,

Job
