今日のappengineは調子悪い?

  • 朝方TaskQueueで下記2つのエラーが頻発していた。
  • TaskQueueなのでエラー時に自動リトライされて最終的には正常終了していた。
  • いつもなら3分で終わる処理が30分ほどかかった。
Request was aborted after waiting too long to attempt to service your request. 
Most likely, this indicates that you have reached your simultaneous active request limit. 
This is almost always due to excessively high latency in your app. 
Please see http://code.google.com/appengine/docs/quotas.html for more details.

quotaと言ってもいままでこんなエラーでなかったんですが、結局正常終了してるし。。。

UnknownExceptionはappengine側でも不明ということか。。。
