[Labs-l] Labs instance hesitations over the coming week

[Andrew Bogott]

Greetings!

I'll be gradually moving most labs instances to new hardware over the 
coming 7-10 days.  For virtually all instances this move will be 
invisible to users -- the worst case scenario is that an instance will 
freeze for a minute or two during the final post-copy sync. I've already 
moved several projects without incident.

Nevertheless, services which have extremely touchy timeouts may error 
out or throw warnings.  For example, a few things in deployment-prep 
sent 'service down' alerts which lasted a few seconds before being 
resolved.  So if you see something like that, it's probably a result of 
the move.

I will be moving the Tools instances first, starting tomorrow morning 
(approximately 14:00 UTC).  The tools migration will take around 18 
hours.  On Friday morning I'll start a scripted move of all other 
instances; the complete move will take around 7 days.

If this process concerns you and you'd like your instances moved at a 
pre-determined time, feel free to contact me off-list and we can make an 
appointment for your project.
