A small but rather far reaching error caused the entire top level domain of Sweden to go missing on Monday, according to Networkworld.com.
"The .SE registry used an incorrectly configured script to update the .se zone, which introduced an error to every single .se domain name," says web monitoring company Pingdom. "We have spoken to a number of industry insiders and what happened is that when updating the data, the script did not add a terminating '.' to the DNS records in the .se zone. That trailing dot is necessary in the settings for DNS to understand that '.se" is the top-level domain. It is a seemingly small detail, but without it, the whole DNS lookup chain broke down."
Sweden's Internet Infrastructure Foundation, which administers the .se domain, issued a statement saying "The cause was an incorrect software update, which, despite our testing procedures were not detected. Thanks to well-functioning surveillance system .SE discovered the error immediately and a new file with the DNS data (zone file) was produced and distributed within one hour. ... The false information that was sent out affected accessibility to all .se domains for a short time. However, there may still be some name servers that have not changed out of misinformation against the real."
The foundation then quickly but quietly posted a help wanted add on Monster.com ;)
