it was better in the last week, down to 2-3 seconds. But not it is
slow as hell again and takes more than 6.5 seconds to fetch a single
tile:

time curl -sSf https://c.tile.openstreetmap.org/11/1100/671.png >/dev/null
real 0m6.587s
user 0m0.017s
sys 0m0.009s

you can repeat the request and it is still slow (5+ seconds).

who is in charge of the HTTPS setup for OSM?
