[routing-wg] Subject: RPKI ROA Deletion: Post-mortem

Agreed, thanks for this Nathalie.

Given the operational importance of RPKI now and each RIRs role therein 
can you say anything about what plans RIPE has to provide 24x7 
monitoring / support for these services (i.e., beyond your current 
"office hours")?

I also look forward to [your] analysis of the Rostelecom incident that 
occurred in the same timeframe.

Thanks,


-danny
