Welcome to Edisen real-time information on system status and security. A note will be posted here if there are any interruptions in service and scheduled service events.
The PBS NOC will be performing uplink testing this week (week of 7/6/26).
Expected interruptions should be no greater than a diversity site switch. Please contact NOC_TECH_MAINT@pbs.org or achorning@pbs.org with questions. Notice of this work has also been posted to myPBS advisories.
Station Impact:
Terrestrial sources for HD01, HD02, HD03, and HD06 will switch at the times indicated in the schedule posted below. There may be a brief interruption in these feeds when the switch occurs at the start and end of the test, and it is expected that the timing of the feeds may be slightly different during the test. Stations who make timing adjustments during this testing period may need to re-adjust when testing is finished.
Upcoming Uplink Testing: Times are EDT (UTC -4)
PBS NOC Uplink Transition Test Plan:
July 9 – 24hr test - ingest and short turn file, uplink switch. • 0900 – PBS OPS posts advisory on myPBS.org • 0955 - EDM TOC contacts PBS SOC requesting access to Galaxy 16 Transponder 22. • 0959 – PBS NOC switches terrestrial MPLS feeds to EDM sources • EDM TOC coordinates with EDM MC to switch uplink. EDM handles email and myPBS.org notifications • EDM monitors myPBS.org and responds as needed.
July 10 • 0900 – EDM TOC posts advisory on myPBS.org • 0955 – PBS SOC contacts EDM TOC requesting access to Galaxy 16 Transponder 22 • 0959 – PBS NOC switches terrestrial MPLS feeds to back to local sources
If you encounter any issues during this time, please notify either the PBS NOC or the Orb Group Support Team:

Interconnection Service Recipients,
From 2026-07-01 21:30 - 23:10 UTC (17:30 - 19:10 EDT), we detected packet loss resulting in lost video and audio across a high number of Live Linear Contribution Streams. The packet loss incident has since resolved, and we are monitoring all streams for stability.
For PBS Platform Streaming, if a failover to the National feed took place, your site can now switch back to your local feed via PBS LLS Admin Console. Please notify any streaming providers that the local feed has been restored, if needed.
We have raised the issue with the national network provider and will be working to have a root cause analysis performed.

Resolved - We have not observed any additional outages, packet loss, or disconnections across any Direct Connect connection or interface over the past four hours. Monitoring remains in place, and all systems have remained stable during this period. Investigation remains open with the network provider and the reason for the outage will be shared in upcoming communications.

Monitoring -
Between 11:42 AM EDT (15:42 UTC) and 12:00 PM EDT (16:00 UTC), AWS Direct Connect traffic for MagnuBox File Delivery in us-east-1 AWS region experienced a disconnection and drop in traffic, which triggered a failover in MagnuBox traffic utilizing this connection to the us-west-2 AWS Direct Connect path.
During rerouting, a small amount of packet loss was observed on linear streams on the separate us-west-2 direct connect between 11:57:24 AM EDT (15:57:24 UTC) and 11:57:27 AM EDT (15:57:27 UTC). The loss was limited to approximately 200–300 packets per linear stream and did not result in any LLS stream failovers.
There is no immediate action required for linear streaming service recipients. Initial investigation indicates a possible BGP issue between the national connectivity provider and AWS and further updates are expected. The Orb Group OSC is actively monitoring traffic and will resolve this incident after a period of heightened monitoring is complete and all systems are confirmed stable.

On Tuesday, June 30, from 8PM-11PM ET (5PM-8PM PT), the Orb Support Team will coordinate a OneVigor software upgrade to the Production Environment.
During this maintenance window, we anticipate no interruption to file delivery or linear delivery. However, the Interconnection Media Management GUI and the Global GUI may be unavailable during this maintenance window.
In the event a service disruption does occur during this window, no action is needed from service recipients. The Maintenance Window will be completed, and normal service should resume no later than 11PM ET (8PM PT).
If a service disruption persists after the maintenance window has ended, please contact the Orb Support Team for assistance.
