late post from Tuesday evening when PNNL disrupted offsite network access for maintenance. The GRB alert system running on h1fescript0 reported that it was unable to contact the GraceDB resource, and then seamlessly reconnected when network access was restored. This outage lasted just over a minute, so the CAL_INJ_CONTROL MEDM screen would have been RED for a few seconds.
