Hi friends,

I am building an app with gmaps and visual studio 2005. Everything is
great with gmaps and I am very happy with it.

However, I want to build a system where, if, the google servers are
down then I can take appropriate actions.

My approach was simple..
1) Get a tile using HTTPWebRequest, pref one that will be small in
size and in the general area of my maps center. eg-

 http://mt0.google.com/mt/v=ap.83&hl=en&x=14&y=10&z=5
 http://mt1.google.com/mt/v=ap.83&hl=en&x=14&y=10&z=5
 http://mt2.google.com/mt/v=ap.83&hl=en&x=14&y=10&z=5
 http://mt3.google.com/mt/v=ap.83&hl=en&x=14&y=10&z=5
(size only 100bytes per tile as image is empty mostly)

2) repeat for mt0 , mt1, mt2 and mt3

3) Test api server by fetching http://maps.google.com/maps?file=api&v=2

4) If all was ok then google maps servers are all up.

The problem is when I make the request for the tile servers I get a
403 forbidden exception. The  API url works without a problem and i
get an OK status.

When Investigating, I found out that the same tile urls work if I put
them in the address bar of my browser(even after clearing all
cookies.. so that is not a problem).

My aim is to revert to the older site model if the maps are not
working or are going too long to load.

I know that the uptime for the google servers is almost 100% but there
are many other factors like my network, long ping times etc..

If there is some service that can be queried for uptime of the servers
then please let me know as it would be much simpler to implement.

Please help. Thanks in advance.
