I first noticed the slow tile servers while visiting the main web site
https://www.openstreetmap.org using a browser. It didn't matter which
browser I used, Safari, Firefox, Google Chrome etc. This was more than
4 weeks ago. Changing the user agent does not speedup anything. You
can use an empty user agent, a random user agent ("foobar") or a real
one, same results. If there is a slow lane, then apparently all user
agent are effected.
Google Chrome reports a page load time of 7 seconds for
https://www.openstreetmap.org which is notable slow and you don't want
use in a presentation or show your mom. If you move the slippymap, it
will takes another 5 seconds.
In contrast, the OpenCycleMap https://www.opencyclemap.org loads in
less than a second (!). For me, both tile servers
(https://a.tile.openstreetmap.org/ and
https://a.tile.thunderforest.com/cycle) are running at the same data
center at hetzner.com (ping time < 20ms). It is unlikely a provider
issue.
I run the tests from different locations (US West, US East, Germany,
Finland) and different providers (Yahoo, Alibaba, Hetzner, Vodafone,
Telefonica) - same results. Big providers may have network slowdowns,
but they usually fix this in minutes or hours.
My gut feeling is that something is wrong with the SSL setup at
tile.openstreetmap.org. Feel free to contact me if you have any
question.

Re: [OSM-dev] slow osm.org tile server
For previous attempts to fix it, please look into
https://github.com/openstreetmap/chef/pull/97 - in 2016 delay pools were
mindlessly set to unusable limits if your ISP happens to have more than a
couple of OpenStreetMap users, and not all the values were raised since
then.
