RPKI Deployment Issue

On 5 March at approximately 12:00 (UTC+1), we deployed a new version of software that publishes data to our RPKI Repository Delta Protocol (RRDP) repository, which started publishing deltas (the changes of the repository) and snapshots (a full copy of the repository of that point in time) that in some RRDP versions did not have a manifest fully corresponding to the objects included or withdrawn in that version.

This resulted in our RRDP repository having the same (eventual) consistency as in the rsync repository, however, some validators were not able to handle it, up to the point that they would drop all known Validated ROA Prefixes (VRPs) announced to the routers via RTR protocol.

We have reverted the change in our software that led to this situation on Friday 6 March 15:00 (UTC+1) and are making sure to avoid such situations in the future by collaborating with Relying Party implementers and router vendors.

We apologise for any inconvenience caused.
