Earlier today, GPS sat PRN 11 was offline for a few hours.  PRN 12 will be offline until tomorrow.  I'm not sure if it is the cause, but my Ublox M8 locked up.  My Venus timing receiver says it is tracking PRN 12.  Most of my other receivers sat PRN 12 is either unhealthy or visible but not being tracked.

Hi Mark,

Both PRN 11 and PRN 12 is listed for outage due to maintenance. During
that period they should not be tracked.

I sent the latest annoucement showing this.

Receivers should follow the health status, and we should monitor if it
is being ignored.

Cheers,
Magnus
