Anyone else noticing sudden increased datastore latency? We have an app that has been behaving just fine and all of sudden (at least some) datastore queries have this large latency.
This is using python2.7 with ndb. I can quickly tell that is the datastore because being logged in/out makes a huge difference. And this difference comes from two additional per user datastore queries.
I also turned on appstats. Interestingly, each of these two queries shows as 3 parallel queries of almost the same exact duration. And these latencies are ranging between 5 seconds and 10 seconds on these queries.
The status dashboard says all green.

I intended to also include the following:
app id : galtsgulchonline
I only had two instances serving just a bit ago and I terminated them both and let the scheduler start new ones. This had no impact on the latency though.

Just following up on my own post ... about 8 to 10 hours after the high latency started for this app, things went back to normal.
