Health service data is not up to date notifications

Question

Health service data is not up to date notifications

Robyn Richardson 40

Since yesterday I've received emails that our Health Data is not up to date. I'm on the latest version of Entra Connect sync, and the services are all started. Entra Connect Sync is working fine. We also got one for 'Password Hash Synchronization heartbeat was skipped' but that has since resolved itself. Is the Health Agent service not working properly in Azure? I don't see any service alerts. But it seems to resolve itself then flip back to 'out of date'.

I'm also having this issue on Entra Connect - exactly as described by Robyn Richardson, Health data not up to date, then it resolves and then it errors again. Started yesterday I think. Over the weekend there was a SQL patch installed, the September 9 one. Don't know if that has anything to do with it.

Same here. First alert was around 3:45pm Eastern 10/7. They have since resolved and reopened several times, but every Sync seems to be running as normal. Latest versions of all services are running.

Several of our customers' tenants have been having the same issue, with at least eight getting either the Health data not up to date or Password Hash Synchronization heartbeat was skipped off and on over the last day or so. Four other have been healthy the whole time, though, so it seems to be affecting most, but not all tenants.

I just received a call back from Microsoft after opening a ticket a couple hours ago. The support agent confirmed there is a known issue going on and there is nothing wrong with our Tenant. Wish they would update the Service Health page with this information so we didn't have to waste time chasing ghosts.

Yes, I also received an alert today. Some alerts were resolved, but then I got another critical alert. Is it a global Issue by Microsoft?

Looks like it must be a Microsoft issue, i haven't received one all day and my alerts appear to be all resolved now. Fingers crossed it stay this way. Thanks everyone!

Answer 1

Here is the written acknowledgement I just received of this being a global issue I got from MS:

My name is XXXX from the Microsoft 365 Support Team. Thank you for taking the time to speak with me regarding the issue with Entra Connect Health, referencing case number XXXXXXXXXX.

Below is a summary of the issue as discussed:

This is a known global issue on our end, and we sincerely apologize for any confusion or inconvenience this may have caused.

I’ve reviewed your tenant’s synchronization status and can confirm that both the Sync cycle and Password Hash Sync are running normally.

Our engineering team is actively investigating and working to mitigate a service incident related to the alerts you’re seeing for Password Hash Synchronization Heartbeat and Health Service Data Freshness.

The root cause was an Event Hub outage in the West US region, which resulted in data upload failures and false alerts across multiple tenants. The Event Hub resource has been scaled up to process the backlog of data, and false alerts raised during the outage period are being resolved. No customer data loss occurred during this incident.
