I'm seeing 90+% of our connection attempts to the MXes for 'hotmail.com'
and other Hotmail domains (mx[1-4].hotmail.com) are either timing out
(30s) or getting connection refused since ~11:00am PDT. Anyone else
seeing this? I've tested from a few off-net points and am seeing the
same. Mail is starting to pile up in our queues in quantity. Given the
scale of what this appears to be I assume the team is already hard at
work on it, but the lack of mention here concerns me, so sorry for the
noise if this is too obvious for the list ;-).
Our primary outbound relays are within 64.253.128.0/19
Here are a couple representative logs:
