What is GitHub using for real-time updates? No more websocket or SSE?

Question

Until recently when I opened the developer tool on a GitHub page I could see an open listening websocket receiving the news for an issue page or a code change or something else real-time.

Today I can't find any websocket connection anymore or SSE calls.

What are they using now for real-time updates or events?

Answer 1

There is nothing mentioned about SSE or websocket on:

• GitHub Engineering
• GitHub blog (and its changelog )
• GitHub public roadmap

So check first if the issue persists over the next few days, because WebSockets or SSE (Server-sent events) should not have silently "vanished" from GitHub pages (although there was a recent incident ).
