Updating in datastore not working in GAE 1.9.0

Question

We have a PHP application running on GAE. It connects to Cloud Datastore using the Google PHP library (v0.6.7).

Google introduced in the last days a new version of App Engine, v1.9.0 (not oficially released), which apparently was running fine, just as 1.8.9 was. However, we have been experiencing some issues related to Cloud Datastore. Sometimes, all the operations regarding to entities updating are just ignored. All the queries used to retrieve information work perfectly, however if we want to create a new entity of update any property, no action is performed. I have been checking for some errors in the response returned by the Cloud Api, but there is no errors or warnings at all.

This situation happened for the first time the 31st of January, and it is also happening today. It started to fail at 3am (GMT +1) and according to the instance log, at the same time the latency times of all the requests suffered an important increase (from 1-3 secs to 5-10 secs). The first time after a few hours the system started to work properly again, but now this problem is lasting much more.

Has anyone experienced anything similar?
