How to read posts on a browser (how to check if a post I sent got to the list)

[rhkramer@gmail.com]

I usually read mail list posts in kmail, but they never show the posts that I 
made (except in the sent mail folder).

I want to see if a post I sent made it to the list.

I tried going to:

https://lists.debian.org/debian-user/2018/10/thrd2.html

debian-user Oct 2018 by thread 

But it says (and has said for at least several minutes):

The last update was on 19:40 GMT Thu Oct 25. There are 859 messages. Page 2 of 
2.

I think that is about 4 hours behind the current time.

So it is not updating in "real time".

Is there another place to read posts on a browser in closer to real time?
