Security Measure: Memcached port block

We have seen an increase of the Memcached DDoS attack method in our Leaseweb Network. To mitigate risk and increase your security, we have decided to actively block the port on our Network. The port that will be blocked is UDP 11211. You can find more information in our applicable Leaseweb Policies sections 7.2 and 7.3.
We recommend that if you are using Memcached, please ensure the service is not listening on a public IP.

In case you have any questions, please do not hesitate to contact us at abusedesk@global.leaseweb.com

Kind regards,
Leaseweb Global B.V.
