As initially announced in 2025, we are planning to retire the GCN Classic VOEvent brokers (https://gcn.gsfc.nasa.gov/voevent.html) on April 6, 2026. This impacts users who utilize the VOEvent Transfer Protocol (VTP) to receive VOEvent-format GCN Classic Notices. VOEvent-format Notices remain available via Kafka and email (https://gcn.nasa.gov/docs/notices/consuming), and we recommend users migrate from VTP to Kafka. For more details on this new feature and an archive of GCN news and announcements, see https://gcn.nasa.gov/news.
