> When a GCP customer uses Google Cloud Load Balancing or Google Cloud CDN to serve and load balance traffic for their website, the content is sent to users' browsers using BBR. This means faster webpage downloads for users of your site.

This makes it sound like BRR is only available for Google-managed services on GCP, is that correct? Can I use BRR on GCE servers (which can install the kernel module)? Seems like an odd thing to leave out.

Yes, you can use BBR inside a VM in GCE. Here is a quick-start guide if you are interested in doing that:

https://github.com/google/bbr/blob/master/Documentation/bbr-...

Note that, in addition to Neal's instructions, you may want to load virtio_net with napi_tx=true

This makes virtio_net play more nicely with the qdisc layer. GCE requests moderately deep Tx queues 4096 -- without the module param you can have up to a 4096 packet delay between actual and as-seen-by-qdisc Tx times.
