Hulu - WI/MN/IL

2023-11-06 Thread Doug Barrett
Does anyone have inside info or fixes to the Hulu problems plaguing WI/IL/MN 
operators over the last 3 days? Customers on Down Detector as well as our own 
CS dept are reporting inability to access, high latency, etc. 

Re: Request for assistance with Verizon FIOS connection

If possible, put a network tap in-between the router and the ONT, and sniff
the traffic.

I've seen this recently where in a very specific circumstance (two hardware
vendors, and only with CGNAT IPs), one side stopped responding to ARP
requests.  The tap capture showed the request going out, but the far end
never processed it.  Running a capture on the far end device wouldn't show
the received ARP request - it just vanished somewhere between the wire and
the pcap.

Solution ended up being a software update on the router side, I'm assuming
it updated a NIC driver as well.
