Problem with problems (or dealing with my ISP)
Sigh, for the past two weeks I have been having intermittent problems with several major web sites, which all happen to be Akamai customers. Akamai offers "high performance content delivery" via their solution called EdgeSuite.
Unfortunately for companies like eBay Canada, Chapters-Indigo, CBC, Analog Devices, and Linear Technologies, it has not been working very well for me, a Cogeco cable modem based High-Speed Internet (Standard, Residential) customer.
So far it has cost Chapters-Indigo a few hundred dollars, and a undetermined amount for eBay Canada in lost sales.
The technical problem appears to be part of Cogeco's internal network is mangling packets.

Compared to accessing a popular web site, not located within Cogeco's network.

Note: The 10.70.128.1 is located within Cogeco's network, it is either a Cisco UBR (Universal Broadband Router) or an IP router.
Of course, I didn't know all this when I first reported the problem, initially for me the problem was that accessing popular sites was flakey, but that doesn't matter really. Now I cannot seem to get this information the Cogeco's internal technical staff. That is the real problem, not getting this more specific, and useful details to the right people.
Oh, well.
