[google-appengine] 5-10 mins of downtime after deployment.
Hey folks, Over the last few months, every now and then when I deploy I have 5 -10 minutes of downtime after I deploy a new version. I'm using python. View the app here: http://triton.ironhelmet.com In the log I get the usual, Compilation Completed, Starting Deployment.. then it checks if the app version is serving for a long timer after that. A few weeks back it actually time out (I think after 15 minutes). During this time all the uses see is Error: Not Found The requested URL / was not found on this server. Now I'm a little afraid to deploy because 10 minutes of down time is a big deal for my users. Is there anything I can do to fix this? Is this an issue on my side? Help!

But 5 - 10 minutes of downtime from deployments on a semi-regular basis, that's something extremely unusual. You might want to try installing AppStats to see if there are any hanging or slow calls during init causing this downtime.

Then you'll have two different versions on App Engine servers - the "old" current-production version and the newly uploaded version. Send some requests to the newly uploaded version, let it spool up and work through its "5 - 10 minute downtime". Then you can change it to the default version on the Versions tab of the admin console. There should be no downtime from the switch. - -Vinny P Technology & Media Advisor Chicago, IL App Engine Code Samples: http://www.learntogoogleit.com -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.

No, there is no start up processing. This only happens perhaps one in 20 updates. I don't really want to bump the version number 3 times a day just in case there is some weird down time. Is this not something other folks are experiencing? I would have thought it might be something you want to look into.

Oh thanks Vinny, I do appreciate you taking the time to make some suggestions. Jay.
