What exactly is the "Hot" portal?

For the uninitiated, "Hot" does not refer to the temperature inside a tram in August. In STIB-MIVB internal jargon, "HOT" stands for "Horaire Opérationnel et Trafic" (Operational Schedule and Traffic).

This is the internal dashboard that answers three critical questions in real-time: It is important to clarify upfront that the

  1. Where is my tram/bus right now? (Not the passenger app estimate, but the raw GPS loop)
  2. Is the "Pre-metro" tunnel under Brussels Central blocked?
  3. Who is driving the 7:15 AM shift from Delta?

While passengers use the STIB app for estimated arrivals, employees use the Hot Portal for deterministic reality.

Frequently Asked Questions (FAQ)

Why does the "Hot" portal matter to riders?

You don't care about /irj/portal/hot—you care about whether the 71 bus is coming. But there is a direct link: What exactly is the "Hot" portal

When there is a "perturbation majeure" (major disruption), the dispatcher panics. They switch from the modern passenger app interface to the Hot portal. Why? Because the passenger app aggregates data (which can have a 30-second lag), but the Hot portal shows the raw track circuits.

If the Hot portal crashes during rush hour (a known issue with legacy Java memory leaks), the dispatcher cannot see where the trains are. Consequently, the passenger app starts showing "No real-time info available."

The Hot portal is the source of truth. Everything else is just a cache.

Q4: I get a blank white page after login.

A: That is a classic SAP portal Java issue. Clear your browser cache, delete cookies for *.stib-mivb.be, and reload. If using Chrome, turn off "Predict network actions to improve page load speed".
