The observability stack behind the World Cup | Deutsche Telekom’s Felix Mohnke & Neha Kumar

13.11.2026 · 28 Min.

Shownotes

When the World Cup arrived, Deutsche Telekom filled a control room with eight big screens of dashboards following customers from booking to payment. Head of observability Felix Mohnke and consultancy team lead Neha Kumar are in the middle of moving 600 applications onto a single observability stack, and they had three months to build dashboards that usually take four. Grafana's AI assistant got them to an 80% version in the first half hour. This week on Dev Interrupted, they join Andrew to walk through a mid-tournament spike in payment outages, traced within minutes to a downed external credit card provider before customers ever noticed.
