+### vac:dst:
+- `eng-10ktool:vac:bandwidth-test`
+    - Delayed simulations.
+    - Finished plotter module tests ready to review (https://github.com/vacp2p/10ksim/pull/19)
+    - Finished data class, related PR already merged (https://github.com/vacp2p/10ksim/pull/16)

+- `eng-10ktool:vac:bandwidth-test`
+    - Many many fixes to get Kubernetes with OpenvSwitch + offloading + VMs working
+        - Reinstalled 3 nodes with new Debian + Proxmox flavour
+        - Installed Mellanox OFED drivers
+        - Experimented with VirtIO network, managed to eventually get SR-IOV and Virtual Functions working
+    - Waku - Benchmarked 1-worker (one worker as one eighth of a 64 core node) cluster
+        - Indications are we can scale to ~14k nodes if scaling is linear, vs CPU usage observed on 1-worker
+        - Had 243 Waku nodes, including publishing, running on the worker or 1/8th node with headroom to spare
+        - Network offloading appears to about 2x as efficient CPU wise when running Waku
+    - Further fixes for offloading setup once SR-IOV was working
+    - Waku - Reinstalled 24 workers, then wiped them all and reinstalled 8 of them :(
+    - Diagnosed incredibly complicated packet loss issues (which turned out to be caused by cloned VMs - note to self - clean up /etc/machine-id next time!)
+    - Waku - Benchmarked 8-worker cluster (1 physical 64-core), scaled to 1200 nodes, hit major issue with Calico
+        - Documented here - https://github.com/projectcalico/calico/issues/8676
+    - Added caching to Harbor, further investigated removing Harbor rate limits
+    - Discovered that adding multiple jobservice workers to Harbor makes rate limits higher
+        - Deployed 6 jobservice workers in Harbor
+    - Removed Vaxis and Nia from Kubernetes to help with CPU accounting since they host worker VMs
