Hi,

Yesterday, there was higher than usual latency in the system, but it
was determined to be within 'normal' bounds:

This does not mean that a specific application will not experience
occasional time outs during such periods. Depending on your
application's resource usage, such instances may still be noticeable.

 Over the past 2 days, my app has been experiencing terrible
 performance fluctuations, even timing out on several occasions for a
 site which has no traffic except for me typing into a browser (for a
 page which typically takes 80ms).  I saw this again this morning
 (2/5) around 8am PST.  In these particular cases, ms-cpu was 1s, but
 actual ms was 9s??

 Is Google infrastructure having a problem?  Performance was terrible
 2/4 late morning, great 2/4 night, and terrible again 2/5 morning.
 The GAE admin dashboard makes it seem that everything is OK.

 Not to confuse the issue, but we recently started using the included
 Django 0.96 framework a couple of weeks ago.  Could that be the
 problem?

 Is anyone else seeing this issue?

I appreciate the fast reply, but we are seeing similar outages this
morning as well.  And not just outages.  Even serving static files
appear to be very slow.  Of course, there's a lot of variability in
all this, too, making diagnosis difficult.
