Spare a thought for the teccies...
The ones at SFDC who are working 24x7 to try and undo this idiocy while the bosses breathe down their necks and the customers continue to call in to ask 'Is it done yet?'.
No excuse for the cretin(s) who broke it, but just remember that there's someone out there surviving on coffee and haribo, who probably hasn't seen wife and kids for 96 hours straight, desperately working to fix it.
This is my territory and I almost took a job at SFDC a year ago that would have put me right on the front-line in this.
AC because $CurrentEmployer doesn't know I interviewed at SFDC!
