The article introduces Approximate Maximum Update Time (AMUT) as a guideline for the maximum expected waiting time for an IdP change to propagate within FIDUS and other FIDUS member federations. AMUT values vary depending on the receiving service provider, with times ranging from 30 minutes for the FIDUS DS to over three hours for services like Beda. These estimates, current as of November 20252024, help schools understand the timing and sequencing involved in metadata updates, ensuring smoother access to FIDUS services.
