Could be when the router was being switched out, Bill.
Was it the same router that caused or was part cause to the outage of last week? I ask because I believe I read on here or over at Idnetters that whilst the outage fault was identified, it was not known why it had happened.
I had then mentioned on my Pings thread that I wondered if the ongoing latency problem was due to hardware still having an "intermittent" type fault and the "balancing" problem was symptomatic of that.
