I've tested some connections I have access to with a pretty interesting result:
- Two BB accesses within AS8404, one got access to [1], the other one not! - One ADSL behind AS21494 works fine. - Upstream traffic over AS13030 works fine.
To me it seems like a large IP block on Akamai spread over several AS, rather than an routing issue.
Here some traces:

Last hop of the one who doesn't work is within NTT in Japan.
