Joshua, your calculation is wrong. A year has 8760 hours, 0.05% of
that time the service can be down -> 8760 * 0.0005 = 4.38 hours of
downtime.

Google had a lot of trouble with their original database, known as M/S. It was
responsible for the downtime you heard about.
So they invented a new database, known as HR, and it has never gone down since
they released it.
So if you use HR (which is the default for new projects), history suggests that
you will not see outages.
But be realistic: Everything goes down. Everything. There is no 100% uptime
guarantee. Google is promising 99.95% which means they are OK with 438 hours
of downtime a year. And that's only a soft promise (like most SLAs, your
recourse is negligible if you suffer losses because of their failures).
I'm quite sure that GAE on HR has better uptime than I could achieve with
anything I could build and manage.

What do you mean by HR?
What I meant is , If I have application hosted in Google Apps Engine ,
will it be affected in the future for example due to data center crash
like what happened before.
We will need this application be available starting from 7 AM to 1 PM
Cairo time. because of this I am asking about the crash time in Google
Apps engine.
I am asking this because my manager wanna be sure our app won't be
available for use. (internal and external).
Also I heard that Google apps engine was down many times and according
to this many companies changed the host from Apps engine to another
PAAS provider.
Another reason for my question is I suggested to develop over Google
Apps Engine for our Customers , but also I told Our management that we
can not trust Google Apps Engine to do this for now , because as you
know and correct me if I am wrong (Google don't care much about Apps
Engine Support)
so my question will be now , can I trust Google Apps engine to use it
for our Clients? in case of yes or no please tell me reasons for your
answer.

Depends how you define "down."
If you only consider HR, it hasn't gone completely down ever. Some bugs have
happened (like losing the ability to send mail to gmail addresses with .'s in
them) which reduced functionality for HR, and there have been times when you
could not update your app. But I don't think HR has ever stopped serving since
it was introduced.
M/S has been down lots of times, sometimes for extended periods. But that's
irrelevant if you are using HR, which you should be if you care about downtime.

I need to know how many time did Google apps engine went down since
launching this service also I need to know for how many hours and what
is the time exactly.
Also I need to know your opinion about the below.
We are planning to develop a product over Google apps engine , a big
project actually for our company.
so should I start using Google apps engine or should I use another
PAAS and if so what is the recommended PAAS.
thx
