The steampowered.com 503s were probably because their seasonal sale started yesterday. Their infrastructure usually doesn't respond well to the sudden change.

I'm not sure it's necessarily DNS related, though, as api.steampowered.com has an A record for 23.214.170.106. The PTR on that is a23-214-170-106.deploy.static.akamaitechnologies.com, though. This is just a correlation; I don't have anything conclusive at the moment, just that it lines up roughly with that noted window. fast.com is similar: Forward is an A record, but reverse on that resolved address is a generated name under deploy.static.akamaitechnologies.com.

Do you have data on the Akamai issue? If so, I?d like to look into it. I would be surprised if we had issues. I see fast.com is on Neustar for DNS:

;; Received 763 bytes from 192.5.6.30#53(a.gtld-servers.net) in 70 ms

This seems to be related to an Akamai change that was made at some point today. Anything that is zone apex mapped at Akamai has been having problems for the last hour or so.
