Somewhat OT, but before I was a jack of all trades enterprise sysadmin, I was a jack of all trades ISP sysadmin.
I'm seeing an issue at a few sites where I have Sophos XG firewalls deployed where the XG gets hammered on it's WAN interface by Akamai hosts with TCP re-transmissions. Anyone at Akamai who may have some background on this issue please reach out to me. The hosts currently in question are 24.244.145.137 and 24.244.145.139, but I suspect that is only due to these being closest to me, colocated at my ISP AS15146.
