RE: Is there an easy way to monitor for Internet failures?

I forgot to ask, did anyone else experience issues Friday, 10am to 2Pm?
Did any of your monitors go off?

As an example of what Roberto is saying is our email system (Notes/Domino) sends out an email to a yahoo account. We paid yahoo a little extra to be able to do stuff like forwarding. That email leaves yahoo and comes into Notes. The Domino agent generates the email, sends it out and monitors a Domino account for it's receipt. If it doesn't happen in a timely fashion than our support is alerted.
It not only tests internet connectivity but it checks true sending and receiving of email and all that entails.

One of the problems is that a simple ping or a query to google does not
the
internet make. The example is pretty obvious. If one of six IPs is having
trouble AND you have no way of testing each one you won't know what is
failing. Ideally you would have a panel where you have DNS status, IP
status of each of the IPs you care about and the routing between. you
might
have spotty returns and that also has to be notified "50% packet loss to
X.X.X.X" is pretty important when that IP is your CC processor...
The reverse is also true. Having a few VPS in different geo locations
testing your own service can help you see if anyone is having trouble
reaching your site. It's not enough that the machine or service is UP,
it's
also important that anyone can reach it.
It's a pretty interesting problem to solve.

Best Regards,

Roberto

What about using GETURI or HTTPAPI to make a simple request to

google.com,

yahoo.com, etc. check the HTTP status code upon return, or monitor for
failures.

If you run web servers on your system, you could check from the outside

in

using something like uptime robot (which is free for a few systems).

For security reasons, ping is usually shut off and not available.

Could you write a small program that periodically "pings" each IP and
check its status?

On Friday morning, Level3 had a major outage, which in turn was
causing intermittent failures for our Curbstone credit card system
which runs on our i5.
It was 4 hours before we were notified that Level3 was the source of
the issue and no problem of ours.

?utm_source=twitterfeed&utm_medium=twitter

Curbstone uses a URL, which rotates to any one of 6 ips, spread

across

the US.
When the IP was used that was in the Level3 outage area is when we
noticed intermittent failures.

Thank You
