[Resolved] The Combined Spam Sources (CSS) component of the Spamhaus dataset had an increase in erroneous listings between 08.06.2025 - 00:00:00 UTC and 09:06:2025 07:10:00 UTC. Data corruption in one of the databases caused this increase in CSS listings. Our engineers have cleared all incorrect listings during this time frame, and the issue is resolved. We apologize for any inconvenience.
