You need to account for the occasional 404 in your script. Just add an && title !~ /404/ should do it. :)

Hi @spyrnmr, thank you for your feedback! I noticed that too and recently changed the announced? method to handle exceptions. In my experience that covers the 404 problem. Or does it still occur?

Ah. Nope that should do it. Wasn't actually using your script, just my own bash script. Was curious what others had built. Didn't realize your exception captured 404's. See you there!

Haha, yeah, let's hope our scripts help us to get a ticket :)

Thanks, @jfahrenkrug. Really nice. Hopefully see you in SFO.
