A single omitted period caused Web sites with Sweden's .se TLD to be inaccessible for at least one hour, with some perhaps remaining inaccessible until the downstream routers refresh their caches. A security bulletin advises administrators noticing difficulties with accessing .se sites to use BIND 9.2.0's rndc flush command to clear memory of cached data prior to a reload. The firm issued a new zone file shortly after the incident, although it admitted it refrained from going through the usual security steps to clear the zone file since .se sites remained inaccessible. A new, fully cleared zone file has since been issued. Some ISPs, for .SE may take two days or longer to fix the issue on their sides of the Internet, said a spokesperson to Sweden's The Local.
