Works for me. I use bookmarks edited to point directly to old.reddit.com.
Try this old.reddit URL and see if it works for you:
https://old.reddit.com/r/talesfromtechsupport/new/
LATER: I notice that the URL now starts with 'https' rather than the original 'http'. I wonder if that's why you're not getting there. Check the URLs in your bookmarks.If you are interested some particular reddit group and teddit.net is "too slow", can set a script to curl that url at some moderate interval. Every 60 minutes seems to be enough for instant access.
Works for me... I used the "Old Reddit Redirect" addon to make sure that is all I will see.
It did not work for me on three separate networks and two devices. New reddit was shown.

Hm, still works for me, e.g. https://old.reddit.com/r/RISCV/new/
