This is not a system glitch or a result of slots being taken instantly. This tactic is employed to manage website load, prevent bot-driven mass bookings, ensure a more uniform distribution of applicants, and align with the consulate's processing capacity. Slots may be added incrementally over subsequent days. This practice is common during peak travel seasons (summer, holidays) and periods of high demand for specific countries. Therefore, a nearly empty calendar should not be interpreted as a lack of future availability; slots are often released in waves.
