Anyone else seeing issues with Google DNS (8.8.8.8) in the Atlanta Market? We have customer's calling in reporting slow or timing out DNS requests. Yes I know this is DNS anycast and have narrowed it down only to the Atlanta Market for traffic going over the Atlant Telx Internet Exchange.
Popular websites that are cached like google, amazon, and yahoo seem fine.
