๐Ÿ›ก OpenBLD.net โ€” Boosting DNS Security & Performance

๐Ÿ”„ The latest release brings major improvements to traffic filtering mechanisms:

RateLimiter has been rewritten to be asynchronous, adaptive, and lock-free โ€” eliminating bottlenecks and stalls under high pressure.

  • Geographic scale-up and user base growth accounted for
  • Enhanced sanitization of malicious traffic
  • Improved handling of parasitic IPs (e.g., abused, noisy, or tunneling endpoints)
  • โšก Increased performance under high concurrency

Noticeable performance gains across European servers โ€” especially under thousands of DNS queries per second.

๐ŸŽฏ Main goal isnโ€™t just to block, but to filter effectively and on time, saving precious milliseconds.

๐Ÿ”„ The update will be done quickly, within a few days, this should not affect anyone, but if suddenly - Welcome)

Thanks to everyone who watches their cyber hygiene with OpenBLD.net.

Peace โœŒ๏ธ
