GoDaddy DNS Outage

Via Wired: Following a day-long Domain Name Service server outage, web hosting provider GoDaddy is letting its competitor, VeriSign, host its DNS servers. Part of me wants to point out that GoDaddy’s relationship with VeriSign’s is not quite that of a competitor. GoDaddy’s primary business is domain registration. VeriSign sold Network Solutions back in 2003. […]

Improving DNS CDN Performance With edns-client-subnet

Several months ago I wrote about how third party DNS services often slow you down since a DNS query is only one part of the equation and many websites use DNS to help their CDN figure out what servers are closest (and fastest). A few proposals to fix this have floated around, one is finally […]

DNS And CDN Performance Implications

I’ve seen various people complain about performance problems when using services like Google’s DNS or OpenDNS. The reason why people generally see these problems is because many large websites live behind Content Distribution Networks (known as a CDN) to serve at least part of their content, or even their entire site. You’re getting a sub-optimal […]

DNSSEC Root Key

Bruce Schneier pointed out that DNSSEC root key has been divided among seven people for security: Part of ICANN’s security scheme is the Domain Name System Security, a security protocol that ensures Web sites are registered and “signed” (this is the security measure built into the Web that ensures when you go to a URL […]

Google DNS Privacy Policy

John Gruber among others note that Google DNS service is not tied to Google Accounts. That’s not just wording in their privacy statement, it’s technically impossible for them to do otherwise, at least with reasonable accuracy. Your computer is associated with a Google account via a cookie given to you when you login. Cookies are […]

Google Public DNS Analysis

Google’s new Public DNS is interesting. They want to lower DNS latency in hopes of speeding up the web. Awesome IP Address This is the most interesting thing to me. I view IP addresses similar to the way Steve Wozniak views phone numbers, though I don’t collect them like he does phone numbers. [Querying whois.arin.net] […]

BitTorrent For HTTP Failover

There is a proposal circulating around the web to create a X-Torrent HTTP header for the purpose of pointing to a torrent file as an alternative way to download a file from an overloaded server. I’ve been an advocate of implementing BitTorrent in browsers in particular Firefox since at least 2004 according to this blog, […]

DNS Strangeness Followup

A few days ago I mentioned I was having some DNS issues. I’m pretty sure they are resolved as the last few days I haven’t seen anything odd. It seems the primary nameserver did not bump the SOA when it updated. As a result one of the other DNS servers was out of sync. Why […]

DNS Strangeness

There’s some DNS funny business going on with this blog the past several days. I’m still trying to figure out exactly where the problem is. DNS has always been one of my least favorite things to deal with.

Me.com DNS Queries

I decided to take another look at me.com, the eve before we all expect a launch at WWDC2008. It’s still using marksmonitor.com for DNS. TTL The TTL is still set to 28800 (8 hours). I think this will drop before 2:00 AM PST (5:00 AM EST) if they are planning to offer email service to […]
