General Availability: Managed Support

November 13th, 2013

Action: You can check out the available Support Plans today.

We are very happy to announce a new support tier called Managed Support. Engine Yard now has three tiers of support:

  • Standard Support: Our team assists you during business hours with planning, deploying and managing your running applications.
  • Premium Support: Available 24x7 and includes additional proactive services such as setting up customized alerting and communications plans (for example, PagerDuty).
  • Managed Support: Provides a wide range of white-glove services where Engine Yard is actively involved in managing your running application on your behalf. Furthermore, Managed Support has additional flexibility to handle very unique customer requirements.

What’s new is that now, for the first time, we will offer the Managed Support tier to customers using Engine Yard on AWS (and, in the future, for Engine Yard on Windows Azure too).

Note: For clarity, the product formerly known as Engine Yard Managed is now Engine Yard on Terremark and will continue to be offered only on our highest service tier: Managed Support.

    Can you provide details on, "New Relic and Nginx reports more accurate processing time for Unicorn and Puma (no longer includes the inbound transit time, which can be substantial from mobile devices)."? I'm wondering if you've changed X-Queue-Start (or similar header) to use ${msec} instead of the old start time? We've been doing this in a custom chef recipe for a while, so I'm trying to see if I can remove ours. I'm not finding what you might have changed or any reference to msec outside of our custom proxy.conf, so am unclear on what specifically EY changed here.

    Hi Christopher. We are now using msec and the change is in proxy.conf. Could you please open a support ticket if you want more info?

    Thank you,

    Thanks Diana, I just verified that (removed our custom recipe and see your proxy.conf is identical to what we had).
