Internet goes down across an organization. What do you do to troubleshoot?

FredTill
You are an IT professional working for a large organization. The internet goes down across the organization and you need to act quickly. What do you do to remain focused and stay calm? What steps would you take to trouble shoot the issue?

My thoughts as well! Anyway, the first place to check is not with your hardware or systems, BUT instead contact your service provider!

NA Slayer that's wrong.

You first check the ISP then Modem and if they are OK work back from there.

I remember a time when the company insisted that the ISP was working and I wasted hours only to finally be told that the ISP was down due to an digging incident where a end loader had knocked over a Power Pole and torn the Fiber Optic Cable and it was in the process of being repaired.

Run a traceroute to an external IP -- by numeric IP, not by name (and preferably one you know will reply, for example 8.8.8.8).
If that just shows you that your packets get through all the way to beyond your ISP, find out why DNS stopped working.

Check the modem?!!! Seriously? If you are a large organization you won't be on a "modem," even a DSL broadband modem. If you are, then that is the problem. You need a complete redesign of your network from the ground up and upgrade of your infrastructure.
