   We've identified an issue with Microsoft's SNDS API where the Blocklist data is returned empty. Our system is keeping its old data in such cases. This means the Microsoft SNDS Blocklist isn't receiving any new data right now. We're waiting for Microsoft to fix this issue on their end. The SNDS Red/Yellow lists are not affected; only the SNDS Blocklist is.
