ACTION REQUIRED: EUMETCast Terrestrial over AMT — Anycast Upgrade

Dear all,

EUMETCast Terrestrial over AMT is being upgraded to support anycast addressing on the GEANT AMT Relays. A new anycast address is now available: 62.40.96.44

This upgrade ensures automatic routing to the nearest AMT Relay, improving reliability and simplifying multicast data distribution.

🔧 For Existing Stations

All existing users should update their AMT configuration to use the new anycast address *before the end of June*. After this date, individual AMT Relay IPs will be retired.

Please follow the update workflow provided here: https://confluence.ecmwf.int/display/EWCLOUDKB/How+to+update+startup+script+for+EUMETCast+Terrestrial+station+on+EWC

This workflow will replace the station’s startup script to support the new anycast configuration.

🔄 For New Stations After 14th May 2025

If you are setting up a new EUMETCast Terrestrial station using the VM available on Morpheus after 14th May 2025, no action is needed — the configuration is already up to date.

If you encounter any issues just contact us via our Support Portal or discussion platform.
