There's no excuse for buried land mines like this to exist. Nobody realizes that you get frozen out of the system for 30+ minutes at a time until you actually get screwed by the system. And no matter what you think you've set your budget to, something can come along and blow it. For example, every night I process a significant volume of CSV data downloaded from a technically unsavvy organization. They seem to delight in finding new and interesting ways to break my (popular third-party) CSV parser. The latest was a name field containing "Blah Blah, Jr" - you can guess what that did. After a few rounds of this I have hacked my parser enough to consume just about any garbage they can feed me. Nevertheless, there were quite a few nights early on where this error caused a large task-queue-driven data processing operation to fail. With the default retry schedule, it quickly ate through my (seemed-to-be-generous-at-the-time) billing quota. Fortunately my technically unsavvy organization is sufficiently clumsy that these problems came up early. If they were only slightly more clever, these issues might not surface until long into production, when it really mattered. As those of us in Javaland were reminded today, GAE fails us every now and then. It needs to fail gracefully. The default over-quota message is WAY more embarrassing than "XYZ is experiencing technical difficulties" - how can we override it? If...you are pretty sure you don't have a bug that is going to cost you > millions of dollars... ...then you are delusional :-) Jeff -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
