Dear colleagues,
At 08:03 UTC, we had a short (partial) outage of about 10 minutes, where
rrdp.ripe.net could not be resolved in DNS. Rsync and the RPKI dashboard were
not affected.
The outage happened after our weekly automated switching between our CDN
providers. During the switch, we verify if our CDN providers are accessible and
resolve correctly. Right after the switch, it appears that there were issues in
resolving the CDN host, which resulted in rrdp.ripe.net being inaccessible for
a short period of time.
This was almost immediately noticed by our monitoring and we reverted the
change in DNS, moving rrdp.ripe.net to point back to our secondary CDN
provider. We have set the TTL to 60 seconds, so the DNS update was quickly
propagated.
Timeline:
08:03 UTC: DNS switch
08:10 UTC: The RPKI team gets alerted that rrdp.ripe.net is down
08:20 UTC: Change is reverted
We have contacted the CDN provider to investigate what the exact issue is.
Kind regards,
Stella
