Introducing new GCN Kafka broker and web site for transient alerts: https://gcn.nasa.gov
We are pleased to introduce the new General Coordinates Network,
the evolution of the Gamma-ray Coordinates Network (now referred
to as GCN Classic) using modern, open-source, reliable, and secure
alert distribution technologies that have been established by the
broader astronomy community and promoted by the Vera C. Rubin
GCN has a redesigned website, https://gcn.nasa.gov and a new
improved method of streaming GCN Notices called GCN Classic over
Kafka, and a self-service configuration of GCN Notices over Email.
All three classic GCN Notice formats (text, VOEvent,
160-byte binary packet) are now also available over Kafka or self-service email. This
new Kafka streaming service can be used as a drop-in replacement
for GCN Classic socket and VOEvent subscribers, and the self-service emails replace
GCN Classic Notice subscriptions.
The web site that you are viewing now (the old GCN Classic web site) and the
legacy socket delivery methods will continue to be supported for
the foreseeable future. However, starting later this year new
features and notice types will only be available on the new web
site and GCN Kafka.

GCN 32419 and GCN 32517.)
