>>A little downtime from time to time can't be avoided. People just love to complain.
If you feel this way then image-editing isn't your core task in your job.
Imagine if the github.com maintainers had your attitude. "Meh, some downtime here 'n there. Whuchagonnado?" A github outage for _OVER 24 HOURS_ would freakin' wreck me and my coworkers. The image-editing department for a high-fashion magazine in New York or Paris with those already near-impossible deadlines losing 24hrs is going to make some execs somewhere very angry.
