Thanks. The app no longer has billing enabled (needed to be able to adjust minimum instances), but that could be worth trying.

[appengine-java] publishing html files
Hie I am generated html documents using a google text doc as template (reading it using gdata apis and then doing some text manipulation). Now, I want to publish these documents somewhere so that I can refer to others giving the url of the document (which means it would be publicly accessible). Any suggestions on how do i go about it? Like where should i host these?

[appengine-java] Whats going on With App Engine?? Feb 24th 7PM EST
All of sudden all requests to my instance are erroring out. This particular instance has was last deployed 12 days ago and there were no issues until today Feb 24 7PM EST. From the logs it appears all request are timing out. Even non-data store operations that are simply initializing the app. 1. 1.

[appengine-java] Re: Slow cold starts
From my experience, an app without billing enabled will encounter many many slow cold starts. That is why although my app visits is small but I still made my app billing enabled. But today, there are suddenly many cold starts again on my app even if it is billing enabled. On Feb 27, 12:30 am, Anders blabl...@gmail.com wrote: Thanks.
