Root cause not identified yet, trying to find possible root cause for that period of time.
Checked radio part and looks fine.
Possibility it might impacted number of sites due to transmission altogether in cluster.
Nothing for particular date on which KPI impacted.
I want to check raw counters of transmission side for pegging during Degradation period in endc ACC.
If any knows or have faced such situation in cluster level, please share.
Actually, it is difficult to do optimization using this method as now you are trying to guess where is the problem and this guess maybe right or wrong, which is completely taking longer time to reach the correct cause, unless you are very lucky
So, my advice is to try to find any counters in the accessibility phase that are affected as well and can help you understand where the problem happened, at which phase, which node is responsible for the failures, etc.
