Recently we’ve added RPKI origin validation to our filters – our own prefixes have been signed since 2017. From now on we will drop ALL prefixes with an invalid origin AS (currently that’s ~2,400 IPv4 and ~900 IPv6 prefixes).
If you think your prefixes are being filtered, please check your configuration.
In addition, we’ve also added filtering based on the Spamhaus blocklists. As with regular filter lists based on IRR, we update these lists every 6 hours.
If you encounter any issues as a result of this, don’t hesitate to contact us.
