+
+FreeBSD Cluster Administration Team members are responsible for managing the machines the Project relies on to synchronize its distributed work and communications.
+
+In this quarter, the team has worked on the following:
+
+* Regular support for FreeBSD.org user accounts.
+* Regular disk and parts support (and replacement) for all physical hosts and mirrors.
+* Cluster software refresh.
+* Coordinate community mirrors.
+* Ports repository history rewrite.
+* Frequent interventions to thwart denial of service by bots.
+* Improvements to cgit on our global mirror network.
+
+==== Cluster refresh
+
+Work continues to refresh the software running on FreeBSD.org cluster machines.
+We have started putting production workloads on stable/15.
+As part of this work some workloads are being moved around to different machines.
+This work is ongoing at the end of the quarter.
+
+The clusteradm team refreshes the production package builders (circa 35 physical machines) on a roughly six- to eight-week cadence.
+These machines run FreeBSD current snapshots.
+
+Other machines are upgraded on an as-needed basis, keeping up with security fixes depending on how exposed they are.
+
+At the time of this writing there are 143 physical machines in the cluster.
+We have 45 machines on current, 33 on stable/15 and 59 on stable/14.
+
+Most of the remaining stable/13 installations will be upgraded to stable/15 or decommissioned.

+==== FreeBSD official mirrors
+
+Current locations are Australia, Brazil, Japan (two full mirror sites), Malaysia, South Africa, Sweden, Taiwan and United States of America -- California, Chicago, New Jersey, and Washington.
+
+Our mirror site in Taiwan is experiencing an extended outage.
+A new mirror site in Taiwan is being deployed at the beginning of 2026Q4.
+
+One of our mirror sites in Japan will get a complete hardware refresh in 2026Q4.

+New official mirrors are always welcome.
+We have noted the benefits of hosting single mirrors at Internet Exchange Points globally, as evidenced by our existing mirrors in Australia, Brazil, and South Africa.
+If you are affiliated with or know of any organizations willing to sponsor a single mirror server, please contact us.
+We are particularly interested in locations in Europe.

+
+==== Ports repository history rewrite
+
+In July a committer inadvertently pushed a large binary file to the ports repository, necessitating a freeze and subsequent rewrite of the history.
+The clusteradm team rewrote the history of the ports tree and ensured that the new history was visible on all our internal and external mirrors in the shortest possible time.
+Improvements were made to our Git infrastructure and automation to prevent this happening again.
+
+==== Large language model scraping
+
+The FreeBSD Project's infrastructure continues to be under constant attack from scrapers collecting training data for large language models ("AI").
+The companies training these models have largely moved scraping operations from their own -- easy to identify -- infrastructure to botnets ("residential proxies"), making them difficult to block at the network edges without significant collateral damage.
+The Cluster Administration Team spent a considerable amount of time again this quarter mitigating these distributed denial of service attacks.
+
+==== Improvements to cgit on our global mirror network
+
+https://cgit.FreeBSD.org is a particularly popular target for trainers of probabilistic malware.
+We experience a constant torrent of scrapers running on infected computers and appliances all around the world.
+To spread the load of these attacks, the clusteradm team increased the number of cgit nodes on our mirrors.
+This quarter we deployed additional https://cgit.FreeBSD.org mirrors in California and in Paris.
