Given a "Delivery Optimization first" strategy:
Using DHCP option 234 alongside with specific group IDs per DHCP currently seems to be the most reliable thing to identify entry-only clients that should share data. Is that correct or did I miss something better?- Jason_Sandys

There's rarely a one size fits all answer which is why there are choices that you can use to tailor the solution to your environment. Generally though, using DO and MCC "best" is about mapping your content sharing and caching to your network topology and infrastructure which in many/most cases mirrors the DHCP scopes in an environment and thus using DHCP often works "best" and is also the easiest to implement. Your mileage may vary though :-)
Hi Andy and Microsoft team, may I know how the traffic flows? Initially, I intended to restrict incoming traffic from the internet to my MCC server. Based on my understanding, I can configure my firewall to only allow traffic from AS8075. Or do I actually need to allow incoming traffic from anywhere? Please correct me if Iām wrong. I basically work at an IXP with around 700+ ASNs and am looking to add MCC into my network.

Hello! This is really an ISP questions and not an enterprise question, but I'll answer it š. There is no way to restrict which CDNs the cache fill will come from today, but something we are looking at implementing in the future.
Are MS Teams updates now supported with DO/Connected cache and if not is it planned to be?

Hi Ian,
To clarify, MS Teams updates are now supported with Connected Cache. You must configure your cache node for HTTPS delivery in order to receive MS Teams content, instructions on how to do so can be found here: HTTPS Support for Microsoft Connected Cache Overview | Microsoft Learn
- Jason_Sandys
No, still not supported to my knowledge. Not sure on roadmap unfortunately. Is this causing significant impact in your environment?
So Delivery Optimization can pull from peers or the Connected Cache server.
- Jason_Sandys
Correct. It can also pull directly from the Internet depending on your requirements and configuration.
Is there any chance that Config Manager distribution points running Connected Cache will be able to report to the Azure portal?
- Andy_Rivas
Hello Joe! Answered during the AMA. No stats for the cache nodes themselves, but if co-managed or cloud-managed and pulling from the DP deployed Connected Cache, then the client data is available in the WufB Reports Monitor Delivery Optimization | Microsoft Learn

Thanks Andy! This topic was covered at 7:28, for all who would like to reference the live AMA.
Will this support GCC and GCC high?
- Pearl-Angeles
In addition to Aditya's response below, this topic was covered during the AMA at 10:42.

There are no immediate plans to support GCC or GCC high for either DO or Microsoft Connected Cache, and I don't have a timeline for you at this moment
In a small office setup, what's the smallest reasonable timeout for devices to wait for MCC? If I set it to several minutes, as was recommended to me, sometimes I see big delays in clients starting to download files in my lab. I wouldn't want my users to experience such delays.
Also, is there a good troubleshooting guide to diagnose why MCC might not be working as quickly as expected?- Pearl-Angeles
The panelists covered this topic during the AMA at 12:29.
It's a small lab, 8 clients, one subnet, MCC on same subnet. Sometimes it works great, but other times the clients wait for 3 minutes before failing over to CDN. Thanks for the advice!
- Andy_Rivas
Logs for this would be great.
Hi, is it possible to avoid having 3 client request DO content before it starts to be added in the MCC cache?
thks- Pearl-Angeles
Thanks for your participation in today's AMA. For reference, this topic was covered at 21:21.

Hello Ian! Answered during the AMA broadcast but for future reference... the Intune CDN is sending the "Vary: Origin" header which instructs the web server running Connected Cache to not cache the content. The CDN when it receives more than 3 requests will not send the header. We are looking at how we can work around this but would also be good feedback to provide to Intune.

Welcome to Tech Community Live and today's AMA on Microsoft Connected Cache and Delivery Optimization! Post your questions here.
Can the cache be prepopulated like WSUS so it's available before the client requests it?
- Andy_Rivas
Answered during the AMA, but there is no content management with Microsoft Connected Cache. It's a transparent cache that is seeded by client requests. Use Autopatch to make "rings" and add a subset of devices that will seed the cache.

Chiming in with the timestamp on when this topic was covered during the AMA: 1:04.
