I have a simple page that reads one row and updates it. Over the past
few YEARS, it has taken < 100ms to process these requests.

All of a sudden the latency has increased to 1000ms. This has
increased my cost by a considerable amount. I know I am using M/S
setup and I don't get concurrency because it is only available for HR
storage (What's the technical reason for that?). I don't want to
upgrade to HR because I don't need it and I do not trust the migration
process.

Can someone please look into this.

It's the end of the financial quarter and GAE needed to make revenue targets ;-)

We're having a lot of issues today. We're getting a lot of 500s "Request was aborted after waiting too long to attempt to service your request." We normally have no problem serving these requests. I'm thinking there is a Datastore slowness issue? (Perhaps related to yesterday)

You do need it because MS has wild performance issues. Like the ones you describe.

Are you still seeing this issue? I have an app that has been running
happily for months and then yesterday it started having much the same
problem you describe. Then, magically about 3 hours ago it returned
to normal performance.

GAE is soo unpredictable...you have an app that costs $.10/day then
spike to $1+ for no reason other than issues with GAE and we foot the
bill. Thanks.

Read https://groups.google.com/forum/?fromgroups#!topic/google-appengine-downtime-notify/3b-VyQGJhr4 and the other post about yesterday's scheduled maintenance.

Yay HRD!!!
