could be some kind of dns issue as well
nslookup from here:
nslookup i.dell.com
Non-authoritative answer:
Name: a569.g.akamai.net
Addresses: 80.67.84.75, 80.67.84.74
Aliases: i.dell.com, img.dell-cidr.akadns.net
img.dell.com.edgesuite.net
nslookup from ip-plus or any other online nslookup i could find:
Non-authoritative answer:
Name: a569.g.akamai.net
Addresses: 212.243.221.214, 212.243.221.208
Aliases: i.dell.com, img.dell-cidr.akadns.net
img.dell.com.edgesuite.net
cleared all caches on our cache-only nameservers; not using forwarders; but still always get the same results back
I'm stumped...

Betreff: [Spam] 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.
Here some traces:
