I had a drop out yesterday at noon which lasted for around 5 minutes, The superhub was still showing as connected with all channels but I had no internet access when it come back online my ping was a couple of ms lower so maybe it was maintenance somewhere further down the line than a local issue.
today:
Last week I had my downstream power drop like a soyuz capsule from around 0 to -10 and lower after several weeks of micro drop outs, the SNR went to 30, this lasted for half an hour before they went back up to around 0 and a SNR at 41 - 42 which is perfect. Guess there have been a few issues here recently. I just wish they would fix the jittery minimum latency I am seeing. This is on two upstreams but I haven't seen many with such graphs as a result of upstream bonding, at least not as pronounced.
