Starting at around 8:30 am EDT (12:30 UTC), a number of sources started to report a widespread Akamai DNS issue. Large web sites, which use Akamai for its DNS service, did no longer resolve. Effected sites are Yahoo, Google, Microsoft, Fedex, Xerox, Apple and likely many others.
Some effected domains removed the Akamai DNS servers and are reachable again using their own DNS servers.
Typically, the domain itself (e.g. 'google.com') still resolves, but popular hostnames, like 'www.google.com' will not resolve. As a result, the web site is no longer reachable.
The effect appears to be world wide. Some of the Akamai servers do respond to pings, but do not respond to DNS queries.
I didn't notice anything, looks like the worst part was during lunch time here in Spain (looong lunch time, lol)
For what I've been told Google didn't work for a bit more than 5 minutes at around 14:30 (GMT+1). I don't know if it was very different from other countries.
