8404 has some Akamai servers inhouse -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Daniel Kamm Sent: mardi, 29. janvier 2008 09:49 To: [EMAIL PROTECTED] Subject: Re: AW: [swinog] Large IP Block at Akamai?
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.
