Subject: Switch to HTTP/3 0RTT Fastly stack for tile
X-Git-Url: https://git.openstreetmap.org/dns.git/commitdiff_plain/2e3dc91285c6960ddbaadbdd8714ebcf953db978

Switch to HTTP/3 0RTT Fastly stack for tile

Use the new hostnames as documented in
https://docs.fastly.com/en/guides/enabling-http3-for-fastly-services#sending-your-http3-traffic-to-fastly

This enables 0RTT and HTTP/3.
