Please see the thread at https://en.wikipedia.org/w/index.php?title=Wikipedia:Village_pump_(WMF)&oldid=1158187547#Difficulty_contacting_Emergency which describes a highly experienced user sending mail to emergency@wikimedia.org and getting no response.
I know it's unlikely there's anything that can be done, but could somebody take a look in the mail logs to see if they can figure out what might have gone wrong and if there's any process improvement which could reduce the risk of this happening again?
