pkg_add issues

Yesterday (1 Jan 2022) I was running pkg_add -u after a sysupgrade and
on most of the larger downloads I was getting premature end of file on
archive and other networking issues and generally poor performance.
This started around 7am and I stepped away around 9am, then continued
trying around 10pm.

My installurl is set to:
https://cdn.openbsd.org/pub/OpenBSD

I finally changed it to (Rochester NY):
https://ftp.usa.openbsd.org/pub/OpenBSD/

and the updates were able to complete and the performance was as
usual.

I am in New Jersey. Is there a way for me to tell what the cdn was
pointing to to help find the slow/sick server?

As of now it still appears overly slow.

Thanks.

Jon
