(4 Jan '24) - KFS outage: Both KFS WebSDRs were offline for several hours due to power disruptions at the receive site related to ongoing electrical work.
- It appears that several rapid-fire power interruptions caused operating system corruption of both KFS WebSDR servers, requiring a site visit to diagnose and correct.
- There have also been occasional, brief Internet outages that are believed to be a result of ongoing, widespread network issues occuring across the Western U.S. over the past few weeks and have been particularly severe in the Bay area.
