Maybe it is maintenance that involves swapping out IPGW servers or turbo buffers and the IPGWs available are reduced.
Could there be some maintenance or upgrades happening at SDO? What about the other beams that share this gateway, like 64 and 66? If folks on beams 64 and 66 also see something like this maybe this is the result of some maintenance at the gateway?
If 64 and 66 are also having issues it makes sense that it's most likely ground station related, yes. I would assume that those beams are routed together into one data stream either at the satellite itself, at the ground station, or a combination of both. So anything is possible. 64 is over Missouri and S. Illinois, 66 is over KY, and 68 is over C. Virginia. To the best of my knowledge those are the only 3 beams routed to SDO.
Regarding 10am: I find it very strange that all the congestion is during business hours. It used to be much later in the day, towards evening. So, perhaps a bunch of people on 64 or 66 (9am CDT, incl Western portion of KY) trying to remote work from home? Kids home from school piling on Disney+? I see a bit here as a slight degradation, still nothing major, but I still do all my heavy lifting before 8am.
