KSA warns Cruks checks may be disrupted during November maintenance
Regulation2 min read
The Netherlands’ KSA warned that maintenance to the BSN register may temporarily disrupt Cruks on 15 and 22 November, from 9:00 to 10:00. Online operators must wait to activate new accounts if they cannot complete a Cruks check; existing users may log in based on an earlier check, subject to a new check once service resumes.
Cruks may be temporarily unavailable because of maintenance, the Dutch gambling regulator KSA warned. The Dutch identity data agency will conduct the work from 9:00 to 10:00 on both days.
Gambling providers must check Cruks before allowing someone to gamble. People registered as self-excluded cannot enter legal online casinos, gaming arcades or Holland Casino venues.
Online operators cannot activate a new player's account if the check cannot be completed during maintenance. Registration must wait until the systems are available again. For new players, the BSN citizen service number is used to verify personal details and create a unique Cruks code.
Online operators may let existing account holders log in during an outage based on an earlier Cruks check. Once the register is available again, operators must check whether those players have since registered for exclusion. A player with an active exclusion must be logged out immediately.
Land-based casinos and gaming arcades may admit new visitors while Cruks is temporarily unavailable. They must check those visitors against Cruks as soon as possible after the outage and end access immediately if a visitor is registered.
A fault in the connection to the BSN system delayed the planned opening of the regulated online gambling market by a day on 1 October 2021. Then-caretaker minister Sander Dekker later said the problem was definitively resolved on 20 October.
A DigiD outage temporarily prevented players from registering in September 2022, while an identity data agency fault stopped checks on new players in November 2022. BSN problems in April 2024 and a population register connection fault in August 2024 affected Cruks. Cruks was difficult to reach during busy Champions League evenings in January 2025 and January 2026. The KSA added servers after the 2026 incident, and a further outage made the register temporarily unavailable in July 2026.
