Well, you have no issues tracing to the destination - and whilst the name resolution output is different to mine, that's to be expected given that oracle's website apparently uses akamai's CDN..
you could try changing your dns servers to google's (8.8.8.8 and 8.8.4.4) which will likely result in you getting served a different IP address for the site and see if that works.. will be interesting to see..
you didn't say what the error message you were getting is?
If it doesn't work after you've changed your dns servers (do another nslookup afterwards and check that you're being given a different IP address to 104.118.23.146) then i suspect that your IP address is potentially being blocked based on some sort of reputation score..
edit: you can check your IP's reputation with akamai here
