The internet connection for the whole of Sweden went down for almost an hour when routine maintenance broke every single .se address. At 9:45pm local time on Monday 12 October, every Swedish website went down, and no emails to or from Swedish domains could be received. Around 900,000 domains were affected. The problem was caused by an "incorrectly configured script" in an update of the .se domain, according to Pingdom, a Swedish web monitoring company.

Sweden's Internet broken by DNS mistake | Royal Pingdom
The problem happened during planned maintenance of the .se domain. The .SE registry used an incorrectly configured script to update the .se zone, which introduced an error to every single .se domain name. 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.

The sites were still up but at wrong adresses. Apparently an extra .se was added making the adress to the swedish Google-page google.se.se instead of just google.se.
