Had something really strange happen this morning.
The doorbell rang about 5 times but there was no-one there & the TV turned itself off.
A message came up on my browser saying no internet connection. Yet my modem remained in sync and I had no loss of PPP session.
No I'm not imagining all this because there was a massive spike of ~3k CRCs & FEC recordings went off the recording scale. According to my line-stats this lasted from 12:48 until 12:51. Presumably some massive burst of RFI/EMI somewhere, yet my SNR recording didn't catch anything, so must have been bursty or pulse like as total of 88 Err Secs over those 3-4 mins.
