I post this to the groups because the Google App Engine Support is neither 
answering my questions I posted to the request form 
(http://code.google.com/support/bin/request.py?contact_type=AppEngineCPURequest)
 
nor increasing the "CPU-minutes/minute" limit.

A few weeks ago (during the last Apple keynote) we redirected all users from 
our german news website (www.mactechnews.de) to the app engine site 
(mtn-live.de/ticker/). We expected about 1000 request per second but in the 
first 5 minutes we received 1500 request per second. Before this event we 
increased the billing dollars but we weren't aware of the "72 
CPU-minutes/minute" limit. It is a very simple website that just fetches 
some entries from the db and renders them to the html. All other resources 
cached "public".

Here are some screenshots that shows the situation:

CPU Seconds / Second:

We think the problem is shown in "cpusecspersec.png": The number of CPU 
seconds per second is larger then 72 (it is about 100).

After so many 500 errors we decided to redirect to our old ticker server 
(which is hosted on windows 2008). Some requests contain this dashboard logs 
message:
Request was aborted after waiting too long to attempt to service your 
request. This may happen sporadically when the App Engine serving 
cluster is under unexpectedly high or uneven load. If you see this 
message frequently, please contact the App Engine team.

But we really want to use App Engine for that and are planning to implement 
more feature like chatting on that page or some other community features... 
but this isn't possible at all if even the simplistic basic page can't be 
handled properly.

So our questions are:

1) Could you please increase the per minute quota ("CPU-minutes/minute") for 
the app id "sy-mtn" ? (The think the next Apple keynote will take place in 
September so it would be great to increase the limit as soon as possible)
2) Do you see any other (per minute) quota that we could reach?

Thanks,
Robert
