jaiku当初被认为twitter最有力的竞争者，不料被google收购之后就没了动静，直至早些时候google宣布将停止jaiku的开发，只进行日常的维护工作，jaiku的代码也将迁移直App Engine，并将开源，也就是说jaiku的开发工作google将不再关心，完全抛给了网民开发者。目前新的API已经可用。
可能google此次也是想利用jaiku来测试和推销它的Google App Engine，如果jaiku重塑辉煌那将是个皆大欢喜的事情，也为Google App Engine的推销工作省了不少事，如果失败了也无所谓，反正jaiku是被google放弃了的项目。

One advantage of cloud computing is that it's an expert's job to keep the centralized computing infrastructure up and running. But even experts have problems, and that's what's going on Tuesday with Google's App Engine.
The service has been having outages Tuesday, according to a mailing list posting Tuesday. App Engine, launched in April and still in "preview release" mode, is a service that lets people create interactive Web applications written in the Python programming language.
"We've experienced several outages during the past 12 hours, the most recent of which started at 6:30 a.m. PDT and is still ongoing. During these outages, a significant percentage of requests resulted in errors. The errors are related to usage of the Datastore," the note said. "We're working hard to determine the cause of these outages and will continue updating as we make progress."
Google didn't immediately respond to a request for comment about the issue.
Update 5:25 p.m. PDT: Google fixed the problem, according to an update notice Google pointed out…
"At around 1:40 p.m. we were able to isolate the issue, and requests are currently serving normally," the update said. "This outage was the result of a bug in our datastore servers and was triggered by a particular class of queries. We have isolated the bug and we're currently working on a fix. Going forward, we're also working to further isolate queries so that in the future a bug like this won't affect the stability of the system as a whole."
