That's the magic of akamai.net. Today this resolves to the following IP
addresses, which just happen to be at my ISP, so I get nearly full speed
downloads for patches :)

% host a248.e.akamai.net
a248.e.akamai.net has address 150.101.98.85 a248.e.akamai.net has
address 150.101.98.72

I'm pretty sure these particular akamai servers have been in place for a
couple of years at least, they are used by windows update and
sun.com/downloads (solaris ISOs for example) as well.
