I'm seeing reports from different spots in the US of difficulty in reaching major sites like Yahoo, MSN, etc. DNS errors seem to be showing in many cases.

It's a problem affecting Akamai - all of Akamai's customers appear to be having problems.

My brother in Montreal can't resolve google.com or google.ca; he just asked me as I was opening this message....

I'm just hoping it's nothing too serious :(

SANS reporting it now:

[isc.incidents.org...]

FYI: A lot of the major players are switching from AkaDNS to static DNS right now in hopes of getting their websites back up.

I'm still unable to reach [google.com...] but [216.239.39.99...] works just fine. I also can't see Yahoo...

The problem resolving hosts seems to be limited to search engine sites.

Google, Yahoo, Alltheweb, Altavista, Lycos, Hotbot are unreachable because their host names "cannot be found";

MSN [http://search.msn.com/] results in "Service Unavailable - DNS failure"

Teoma, Ask Jeeves, and various 'smaller' search engines are reachable however.

Seems like somebody's up to something nefarious, no?

At the moment from the UK I get 'DNS failure' for MSN, and I also cannot reach Lycos or Hotbot. I tried MSN through a US proxy and got 'Service Unavailable'. Strange...

For me, Google, Lycos.com, Altavista, Alltheweb dont return even the ip address from a ping.

I agreee, all other sites seem to be fine. Some sort of virus, DOS attack targeting the major engines?

Im in the UK

It's an Akamai DNS issue. Yahoo, MSN, Google, Apple, etc. all having problems this morning, because they all use Akamai.

The DNS system that matches named addresses to IP addresses appears to have been hacked in some way, making many of the world's major search engines, including Google, Yahoo, and MSN Search unreachable this morning.

The search engines themselves do not appear to have been hacked, since they are reachable by the numeric IP addresses of their web servers.

The attack appears to be targeting search engines but not other kinds of sites. For example, Microsoft's MSN web portal site is reachable by Internet users but its MSN search is not.

Does this phenomenon extend beyond search engines?

hacked

No, it's a problem at Akamai.

Yes, it does extend beyond search engines to any of Akamai's customers.

Wow. That sounds like a major 'eggs all in one basket' mistake! Why oh why would it be like that?

Akamai is the only place w/enough infrastructure and bandwidth to support those sites - which makes them a constant target for DOS attacks.

Thanks for the explanation, BakedJake!

They seem to have just fixed things over at Google -- I can reach Google, Google News and MSN search. Still can't get to Yahoo, though.

fixed things

They switched from AkaDNS to static DNS. Yahoo's in the process of doing the same thing - the main pages work, but not the login system yet.

Akamai is still very broken.

[apnews.excite.com...]

Young called it a "large scale, international attack on Internet infrastructure." However, there was no evidence that non-Akamai infrastructure was affected.

Thanks for the story link, bakedjake. And the punchline:

Shares of Akamai were up 71 cents, to $15.62, in Tuesday trading on the Nasdaq Stock Market.

Was getting errors yesterday while accessing gmail.com, now it all works good.

Have they fixed it?
