Feature Service - Error 503: Service Unavailable

[JakubMalec]

Hi,

About 6 days ago we have noticed, that there is an issue with some of our Feature Services hosted on ArcGIS Online.
What's happening is that roughly every tenth request to the service returns a 503 error (service unavailable).

Here are two of the services affected:
http://services1.arcgis.com/mQcAehnytds8jMvo/arcgis/rest/services/Roztocze/FeatureServer
http://services1.arcgis.com/mQcAehnytds8jMvo/arcgis/rest/services/powiatlubartowski/FeatureServer

They are not publicly accessible, but our Flex apps use them through App logins (https://developers.arcgis.com/authentication/app-logins.html)

The problem can by reproduced by simply refreshing the service page several times using CTRL + F5 until it throws an error.

We've made sure that the problem isn't only for our Network. In fact I've tested the service from remote servers based in different countries (including US).

Our applications that use those layers, can't load 1/10th of them, 1/10th of queries fail and our app users don't like all of those error messages :/. We would be glad if anyone here could look into this issue.

Regards,
Jakub Malec

Mike,

We too have been having problems accessing feature services either through the Online WebMap viewer or through our own js api apps.  It seems to have started a few weeks ago when we overwrote a bunch of feature services from ArcMap.

Thank you for your help. All of the services seem to be working flawlessly now;]

The issue where every 10th request was failing has been cleared up.

@PinnGIS, if you are still experiencing problems, we would need more detail and a way to reproduce the problem.

Thanks,

Mike

Hi Mike, any other occurrences of this that you have seen?  I think I'm experiencing something similar.  I'm accessing a hosted feature service with python, the REST API, and HTTP.  I have 9 layers in my feature service that I access individually and I get a 503 error on different layers randomly.  I've seen the error only once when accessing the service through a browser.  My script was working without errors until about a week ago.  Any ideas?

I'm not aware of any issues. I'll run this by the team...

@MikeMinami I am having the 503 error when trying to access hosted feature layers in an ArcGIS Pro model, while also having this error in ArcGIS Velocity trying to access the same hosted feature layers.  Any idea why this is still happening?

Looks like there may have been some issues on the 28th with hosted services https://status.arcgis.com/

If you continue to have issues, I'd suggest contacting Esri Support.
