(think of a common site that gets pinged whenever someone wants to test to see if their connection went down or if it's just loaded.. Limit ICMP into them impropperly and lots of folks notice.) Such limiting also has to undergo periodic tuning as traffic levels increase, traffic patterns shift, and so forth.Along these lines, how does this limiting affect akamai or other 'ping for distance' type localization services? I'd think their data would get somewhat skewed, right?
Perhaps they'll come up with a more advanced system of monitoring? probally the best way to do that is to track the download speed either with cookies (with subnet info) or by subnet only to determine the best localization. With an imperfect system of tracking localization, you will get imperfect results. - jared -- Jared Mauch | pgp key available via finger from jared () puck nether net clue++; | http://puck.nether.net/~jared/ My statements are only mine.
