And email notifications from the tracker are now over two hours old.

That's just from the backlog from sending out the bulk email about the release. It is actually almost caught up so emails will be normal in less than one hour.

It's not under attack we just released 3.4.2 so everyone and their mother is accessing us :smile:

Looks like you are using some sort of CDN for www.invisionpower.com and the node that I get has been unresponsive for 3 hours or so. Here is a dig and ping:

That's interesting as that is not at all what I get for dig:

dig invisionpower.com

That's interesting as that is not at all what I get for dig:

You need to "dig www.invisionpower.com". It is the "www" domain that you seem to have on a CDN. I still have no connectivity to "www" and therefore cannot download the new IPB.

I think your DNS for the CDN needs to recognize that the node I connect to is down and to change the DNS to use another node. I am in Northern Virginia and the CDN seems to be at LiquidWeb (traceroute below):

The traceroute hangs at "15".

I have a related DNS issue but it's with not receiving email notifications because there's no RDNS (either it does not exist or is incorrect). Spamdyke drops the emails for failing RDNS, I could of course whitelist Invision's domain but since this is such a basic requirement for email this may be affecting others. Addressing the problem locally is better than requesting everyone in the world whitelist *invisionpower.com, I thought I'd try to catch a snippet of the failure when someone replies to this thread so someone can give this to one of the network people.

Sorry for the derail

In addition looking at this from two different points.

Iiiiiinteresting. We're looking at it now.

Send me an email if you would like me to get you 3.4.2 before we address this.

The CDN node is still down, but I figured out a workaround and have downloaded 3.4.2.

I just set www.invisionpower.com to 141.101.112.30 in my local /etc/hosts file (which is one of the IPs for invisionpower.com).

Note that with www.invisionpower.com inaccessible to me, I couldn't log into the forum (I had logged out to see if it made any difference, only to find out I couldn't log back in).
