Hey Peter,
Thank you for your patience! These outages are being caused by what we call handoffs. When a satellite and your dish need to switch, the time in between is called a handoff. These handoffs can happen roughly every 90 seconds and will not impact most user applications. Short outages less than 1 second long are generally too short to be noticeable in most cases, and shouldn't interrupt service. We try to be as transparent as possible which is why that information is included in the outage report. The app shares that these are most noticeable in online video games or video calls.
This is something that can vary as we make changes to our constellation, which is why you may not have experienced these before, and currently do. It is not uncommon to see these, and have them go away after some time has passed. We do not have any sort of time frame on when the handoff related outages will go away. We are always striving to make improvements to our overall network, whether it's more satellite launches, or making updates for our ground infrastructure!
Do you have any additional questions that we could help with at this time?
All I can comment is that it is a new behavior, it does impact service, and it is noticeable, which is why I looked into it. From the middle paragraph, it sounds like they know they have equipment issues on their end.
All the best,
Peter
