Hi OSM Dev,

I have experimentally enabled TCP Fast Open (TFO) on the imagery site:

I am interested in any feedback... Does the site not work from any
connections, operating system or software? Improved performance on
high latency slow connections?

TFO is a "new" way to speed up establishing TCP connections.

I'd like to see TFO rolled out to more services in OSM over time.
Depending how things go, next up would be the tile.openstreetmap.org caches.

Kind regards,


Part of the OSM ops team
