I'm not sure where to post this...
« on: March 17, 2025, 11:36:59 pm »

... please move it as appropriate.

OK, I usually access this forum by typing jriver.com into the browser, and then following the links to get to interact.

But this evening, when I enter jriver.com into my browser, I see...

The following error was encountered while trying to retrieve the URL: http://jriver.com/

    Connection to 216.14.187.161 failed.

The system returned: (61) Connection refused

The remote host or network may be down. Please try the request again.

So, then i tried www.jriver.com, and, well, here I am.

More info ...

jriver.com had always worked for me, now it seems to have issues.

What changed?

The servers moved over night, it should hopefully all settle soon.

Your old DNS record had a TTL of 6 or 7 days, so access may be disrupted for some users for up to a week depending on which DNS server they use and how old their DNS cache is :/
You may want to add a temporary 'newyabb.jriver.com' and use it on the main jriver page link until this settles. A new SSL certificate may be needed for that.
Alternatively, set up 216.14.187.174 as a transparently router/forwarder to 216.14.187.173.

Access works for me with 8.8.8.8 as the DNS server, but not with my ISP's DNS.

    QUESTIONS:
        yabb.jriver.com, type = ANY, class = IN
    ANSWERS:
    ->  yabb.jriver.com
        internet address = 216.14.187.174
        ttl = 534366 (6 days 4 hours 26 mins 6 secs)

New server has 6 hours TTL, more sensible.

        yabb.jriver.com, type = ANY, class = IN
    ANSWERS:

        internet address = 216.14.187.173
        ttl = 21600 (6 hours)

Thanks for that.

Before I make such changes on my servers, I always lower the TTL of the DNS entries to an hour or so to reduce these types of issues.

Once things settle, I then increase the TTL of the DNS entries.

Long term?  I'd say, questionable.

But during transition evens, a TTL of an hour (or less, if your DNS provider supports it) is more sensible, imo.  That's how I handle my server.  The question becomes, how much difficulty do you want the users of your site to experience?

But I will say, YMMV.

It depends upon how the site owner wants to enable or restrict site access.
