Some IPs have changed due to the respective providers doing .... things.

Istanbul: IPv4 and IPv6 have changed. Jakarta: IPv4 has changed. New York: IPv4 and IPv6 have changed.

The resolver lists have been updated accordingly.

One of the resolvers in Los Angeles (lax02) is currently unreachable over IPv6. I am in touch with the provider and hope to have this resolved soon.

The resolver in Houston (iah01) had a RAID failure and all data is lost. I have reprovisioned the server and it should be working fine.

The provider hosting the resolver in Tampa, FL informed me about an IPv6 change today. The resolver lists have been updated accordingly.

The provider has assigned a new IPv6 subnet to the resolver in Bengaluru again to resolve some kind of issue.

They seem to be completely clueless about what they're doing, so if this keeps going, I will decommission the resolver again. Apologies for the inconvenience.

Thanks to a generous donation by whoami, there's now a resolver in Perth, Australia at your service
