Some users can't access the site since migration to Community Cloud

[iancassel]

Looks like the CNAME records I setup resolve different IP addresses (round robin) depending on geo location. Some of these locations our users are getting a "Not Found" in their browser. This IP works: 13.32.27.115 (I'm in Europe) and one of our Admins gets this IP address: 108.156.91.25 (he's in Chicago) and its failing. I had him do a "ipconfig /flushdns" and no dice. Many user complaints now about this. Some have no issues, others, it's completely unreachable.

looks like 108.156.91.25 is up now. There might be others still down. By why doesn't the network status page reflect partial outages?

It's happening to me now, IP address for Europe (resolved DNS) changed too: 13.32.27.51

Various IP addresses are expected depending on region due to the CDN used to deliver our Cloud.

Unfortunately (or rather fortunately), I am not having any issues with access myself. Additionally, that "Not Found" should not be exposed on our Cloud (we have a standard cloud error page). Could I confirm that you are not routing this through CloudFlare (bypass mode is on)?

Has it had enough time to propagate?

@Jim M yes bypass is and has been on:

It's been a week, and I did check and emailed IPS, showing some of the CNAME forwards to their DNS is not propagating. The issue is some IPs work and some don't I've discovered some users in the US have luck of the draw and get a defunct one, it certainly pings, but it doesn't load the site. And I just ran into the issue here myself in Europe with the IP I posted above, which just changed again in the last 5 minutes and is working now. 

I've discovered 2 IP addresses that are broken on your round robin DNS:

US: 108.156.91.25

EU: 13.32.27.51

It shouldn't be that hard to trace the issue.

@Jim M Jim all you have to do to troubleshoot is to change your hosts (linux/Mac: /etc/hosts) and put this in there:
 

forums.microcapclub.com 13.32.27.51

and then flush your DNS, and you to can unfortunately experience what ours users are experiencing. ;-)

Thank you for verifying that the DNS is in bypass mode. I have moved this to a ticket so we can better investigate.

@Jim M Jim I sent an email to support (our migration thread, we only just moved to your cloud yesterday) almost 2 hours ago, but wasn't getting a response which is why I opened it here.
