Re: Packet Loss After Maintenance
Thanks for taking an interest,here is the latest update from Virgin Support regarding the ticket status,
F002279284 was closed as fixed on Wednesday. That ticket did have a fairly wide scope however (multiple cables), and a more local one has been opened under the new reference F002287892 for a continuing Forward Error Correction issue on your cable.
The estimated fix date for this ticket is the 28th. Please bump the thread for updates.

The T3 timeouts seem to go so high and the reset to zero is there a max limit on the count for them? the modem was rebooted by me at 12.30.pm Friday and after the restart the T3 errors was zero so there has been 90 T3s in about 10 hours.
What is a Forward Error Correction issue?
PS I've also noticed I'm now on a different US channel number (was 58 is now 59)
