[Labs-announce] Switching to new puppetmaster tomorrow

[Andrew Bogott]

Tomorrow (2017-08-04) at around 15:00 UTC I'm going to start moving 
cloud instances to a new puppetmaster.  This shouldn't require any 
action from anyone else, and will probably not be noticeable.  If things 
go poorly you might get a bunch of puppet failure email spam or alerts 
through other channels.

This will only affect instances that use the standard upstream 
puppetmaster (currently labs-puppetmaster-eqiad.wikimedia.org). 
Instances using a project-local puppetmaster will be unaffected.

I'll send an 'all clear' email when I finish moving things over; after 
that I'll be interested in hearing about any ill effects that remain.
