No I'm not affiliated with Hughes in any manner other than an 11 yr Hughes subscriber.
I can to the realization long ago that the state of the Hughes phone support made it mandatory that I learn as much about my system as I could. It has saved me a lot of "phone time" and frustration over the years.
As to the starting date of the log ... its just an arbitrary date .. a "null value" that serves as a starting point for logging to begin.
Many of the errors that "log" are very brief, very transitory .... many weather related.
You have to remember that bad weather can exist in a line between your "dish" and the satellite (Echostar17 located at 107.1' W. for Gen4 systems (HT1000/1100)) but also in a line between the satellite and the Hughes NOC (Network Operations Center) where your signal returns to earth.
It can be bright and sunny over your house and hurricane conditions over the NOC will have a drastic effect on your system performance.
After all, its Satellite not ground based ... it isn't, it can't be .. the equal of cable or DSL or even a WISP.
There simply are more non moving "moving parts" that add to the complexity in addition to the normal Internet structure.
Its the price we pay for living in an non urban environment.
But as an example of the "errors" that accumulate ... here is a snip of my well running system .... "transitions & duration" are the key parameters.
