Late September was bad for the datastore. We were seeing latency on simple queries vary from 50ms up to 5s. These were simple properly-value queries as well. This was fixed in early October I think, and a recent bit of maintenance brought latencies down even further. The datastore is now extremely fast and rarely errors out.

We (http://gri.pe) are still happy on AppEngine, even though September was rough.

Very true. The datastore unreliability was a real nightmare. I was getting periods of 60 seconds where it was unusable...

But it does appear to be fixed now.

The Datastore problems have indeed been fixed and things have been smooth since the fix.
