We're observing a significant increase in API failures when fetching blacklisting data from the Microsoft SNDS platform. They have recently (4 Dec 2025) performed some changes in how their API works, and we believe these errors might be related to that. Our system has been configured for such scenarios and will fallback onto older/stale data if it cannot fetch fresh blacklisting data from the SNDS API. This may cause delayed blacklisting/delisting notices on the Microsoft SNDS blacklists. Unfortunately, this issue is out of our hands, and we hope they'll fix their API soon so our system can resume regular monitoring of the Microsoft SNDS blacklists. In the meantime, we're keeping an eye on the situation as it progresses.
