Short and sweet: The resolver in Moscow had its IPs updated.
This will likely be the last update for this year, therefore I wish you all a joyful Christmas season and a fantastic start to the New Year. Stay healthy, stay safe and enjoy some time with your friends and family!
Düsseldorf 01 has been replaced and a third resolver in Düsseldorf has been added for redundancy. Many thanks to Luca for sponsoring the VM!
Las Vegas has been replaced by a new VM, please update our IP records if needed!
Fremont 01 has been offline for a while and its successor in San Jose is live now.
The Minneapolis resolver has been taken offline as announced. It's a week early, sorry for that!
Some additional resolvers have been put in service:
Please let me know if you see any issues with these (or any other) resolvers.
Here's the final update regarding the OS upgrades for now:
Valdivia and Johannesburg are back online. Frankfurt (01) is back online as well with an updated IP address.
Replacing the Fremont (01) resolver by a new resolver in San Jose is still pending.
Düsseldorf (01) will stay as-is for now. The provider doesn't offer me an option to install a newer OS at the moment. For good measure, please switch to Düsseldorf (02).
Things didn't go as smooth as expected, so here's the current status:
These resolvers will remain offline until further notice:
These got stuck in the OS installation process and I'm waiting for the providers to get back to me.
These resolvers will be back online within the next hour:
We will be performing scheduled operating system upgrades across several resolvers.
The maintenance window is:
