Hey folks,
I had an unusual issue today; 2.5Gbps uplink started flapping earlier today. Did the usual? turn off auto negotiate to Gbe, swapped ports on both ends, swapped cables – still reporting "multiple outages on ISP" and WAN.
Because multiple google cloud issues reported in the IT world, I added WAN SLA to ping quad9 or cloudflsre and suddenly all up.
The only issue would be the default internet verification service should be ping.ui.com which resolves to both cloudflare and google dns and target than keeping the link up, it brings it up and down (it's a single link with the default failover mode)
Any one else have this issue?
