If you’ve noticed assorted web sites across the globe offline this morning, it may be that they are using ZoneEdit’s DNS servers. There are reports from a variety of places that starting around 4:15am Pacific, ZoneEdit’s ns9 and ns13 servers went offline. Those domains set up with the default two DNS servers (and if they used this two) had issues. Those web servers with at least 3 DNS servers listed were fine.
ZoneEdit has not responded to queries, and as of 7am pacific the issue continues.
NetAdmins: Moral of the story is that you should have 3 and even 4 DNS servers listed for your important domains.
