- investigating Feb 13, 2026, 04:11 PM UTC
We are investigating an issue with DNS resolution for public IP addresses within 31.89.0.0/24. We are engaging with AWS support to remediate the situation.
- identified Feb 13, 2026, 04:42 PM UTC
We have identified the root cause and are working on backfilling those records with AWS support. We have also disabled that ip range for new clusters so moving forward this issue will not be hit for new AWS clusters.
- resolved Feb 13, 2026, 05:57 PM UTC
The DNS records have been backfilled and clusters that had these IP addresses should be recovered.
