Terminology defined. Easy Questions

What's defined as a hot-cut?  
-Using existing rack/cables?
-Do outages go hand in hand with hot-cuts?  Or are outages/blackouts defined as operations 'ignoring' the flags that occurring, or is it an actual 'outage'.  

What is swinging? (L3 swing, swing over L3, etc.)
-Is this 'swinging' IP schemas?  Original is 10.0.1.0/24, new devices will be 10.0.2.0/24.  Maybe the schema is the same?  It could mean a lot of things as well, but elaborate!

If ISP is on the call with us, what are some validation commands I should ask for (QoS, MPLS, basic connectivity)?  Please list!

show ip interface brief....etc.

So the terminology you are asking about is very subjective as to who is saying and what they like to call things.

In general a hot cut is basically a live cut.  There will generally be an outage while things are cut over.

Swinging - not a general term with a specific meaning.  I might use it if we are putting in a new circuit to replace an existing circuit and I would say we are going to swing over to the new circuit.  I might have used the word "swing" instead of "cut" as in cut over to the new circuit.

I have never heard swinging in terms of changing IP addressing.  That is usually referred to as changing your IP addressing ;)

To validate -
Make sure you can ping the connected ISP router, make sure you can ping out to things on the internet i.e. www.google.com, 8.8.8.8, etc..
Make sure there are no CRCs or errors on the circuit.
Test everything - i.e. web browsing, email, verify your hosted severs if any can be reached from the outside, etc..

BTW... I didn't reference your outage questions.  An outage is exactly what it says.  Things will be down during an outage.

Can you elaborate on outages? How are things down during an outage? Do they just turn off the power, or power down switches?  If I schedule an outage what exactly happens? what about situations where a building has multiple tenants, networks or shared comm rooms?
Ken BooneNetwork ConsultantCommented:
So if you are changing ISP or perhaps someone might say cutting over to a new ISP.  There is a point at time in which you will disconnect the equipment from your router/firewall  from the old ISP and plug it into the new ISP.  During that timeframe there is an outage.  This would be an internet outage.  So anyone using that connection will not have internet until the new ISP is connected and working properly.  

If for instance you are upgrading your switches, you would have an outage while the switches reboot.  In that case it a complete network outage that will last until the switches come back up with the new code.

When you schedule an outage you are simply setting a time frame at which users may not have internet/network access.  So you might schedule an outage after business hours between 5pm and 6pm to change ISPs.  The actual time you are down might be as little as a couple of minutes if everything is done properly.  If there are configuration issues or troubleshooting that needs to occur then it might take longer.

In a multi tenant environment it depends.  If they are sharing the network resources, and the network resources need to go down for an upgrade, everyone takes a hit.  Just because they share the comm room doesn't necessarily mean anything for all the tenants.  They might share a comm room but each tenant might have their own ISP connection, their own switches, their own phone systems.  In that case the outage occurs only on the customers whose equipment you are touching.  If the equipment is shared then everyone will take the outage.  This is why you typically schedule these things for off hours and give everyone advanced notice.

An outage is really when we have a loss of something - network, phone system, internet, etc..  So it could be that there is an upgrade scheduled on the phone system.  Ok there is a point at time that the phones will go down, while the upgrade is installed.  Well that would be a phone outage.  It might be that you are upgrading a switch in a remote data closet in the building.  Well that would be an outage while that switch reboots, but it would only affect the users connected to that switch.

Hope that helps.
