"The Cat ate my modem....."

It's good to have a technology backup plan, because, well, Stuff Happens.  

Sometimes you can't attend your own virtual meeting.  You can't hang up on your Vice President, and you are supposed to be running a team scrum that started 3 minutes ago.  Or you suddenly have to drive a relative to the ER.  Or your doctor's appointment runs late. 

It's best if you prepare in advance for this. It will happen.

First, if your e-meeting tool and corporate policy allows it,  give other people on your team the ability to start and run your e-meeting.  If your teammates can start your meeting, they can run that scrum just fine without you.  At most, you might have to text someone -- "start without me!"   Even better, if you know in advance you might be held up by your VP,  you can ask someone else to be scrummaster if you don't show.  

I do not recommend sending out someone else's e-meeting link at the last minute -- inevitably some attendees won't see the calendar update, and your backup host will spend the first 15 minutes of the meeting finding everyone.  And probably failing.  Better to cancel and reschedule than waste everyone's time. 

If having additional meeting hosts isn't allowed,  then next best is for you to have multiple devices to connect to e-meetings.   I can be on one meeting on my laptop, and start another on my cell phone.  I don't recommend trying to actually participate in two meetings at once. I know people who do this, and I have absolutely no idea how they acquired that superpower.  

Remember Stuff Happens for your meeting attendees too.   If you have it, put the telephone call in information in your meeting invitations, as well as an internet link.  As improbable as it seems in today's world,  sometimes people have access to a phone, but not the internet. I had a teammate knocked off the grid when the cat chewed through a cable modem wire; she still made it to a critical planning meeting with the telephone call in.

As long as we're talking about technology backups -- your cell phone and laptop are being backed up regularly, right?  RIGHT?  If you are not sure, go check on that right now, because....Stuff Happens.
