I'd be pinging for 24 hours at 3 second intervals. Are there any IP
addresses out there that exist just for pinging, if not, would it be
considered rude to pick a major site such a google?
Or - let me back up here - is there some other, better way to monitor
internet connection stability using .Net?

What if google is "out of service" and doesn't reply to your ping? Then
you would assume that there is no internet connection even if all other
websites can be reached.

I think the point he is saying is there is no guaruntee that one IP is going
to be up 100% of the time..
That woudl mean a series of routers would have to be up 100%.. which as you
move through the "internet chain" would require every router to be up and
functioning at 100% of the time...
simply, the problem isn't the IP address to ping, however the stability of
all the connections between you and the IP...
oooohhhhh philsophical even... =)

I suggest you ask your ISP if they have a server which you can ping
frequently. The most typical problem is the first hop, so if you can reach
any server at your ISP, then you are 'connected' to your ISP. If that
succeeds, then pick 3 or 4 major sites and ping them at a much slower
interval (~ 2 minutes); then use the results to vote on whether your ISP is
connected to the Internet.
Another option: use SNMP to retrieve the outgoing and incoming byte counts,
on the WAN port of your router/firewall. If the answers freeze at the same
number, then the link is down.

How on earth do you consider that irrelevant? The stability isn't dependent
on the server your pinging, but the routers in between
Whether or not yo ping multiple ip addresses your going to be faced with the
resounding question "what determines if its actually 'down'" Just because
you can't reach a series of hosts doesn't mean you've lost connection, just
no route is possible at the time. At which point does that qualifiy "no
connection"
If I were to do it, get your default gateway through WMI or another method,
ping that.. if you get no response.. your down...

I'm writing an application that needs to know if an Internet connection

Hello all,
we are running a delphi application with DB2 V8.01 which is causing
deadlocks when rows are being inserted into a table. Attaching the
Event Monitor Log (DEADLOCKS WITH DETAILS) here. From the log it looks
like the problem happens when 2 threads insert 1 record each in the
same table and then try to aquire a NS (Next Key Share)
lock on the record inserterd by the other thread.
