Discussion on: What does your team do when your communication channels go down?

Our internal comms tool is also the internal comms tool for a significant portion of the NHS in the UK.

It runs the same technology used in battlefields by armed forces around the world. Also the same technology used in battlefields of a different kind, like Fortnite, and Eve Online. The same technology is used for the Belgian ambulance app, too.

Both the technology and our deployment are designed to handle the kinds of "adverse network conditions" that would cause Slack and friends to stop working entirely - they didn't build hospitals for good WiFi, it seems, and the armed forces run over seriously low and laggy networks, too.

If we're running into performance issues, we all stop what we're doing and fix it - the fact our communication is down is the least of our concerns. But thankfully, we've never had problems worse than a few slow operations. I really hope that continues. :-)

Oh, the technology? XMPP. Open standard, open source, and yes, you can run your own server.
