Is anyone experiencing timeouts when querying 209.244.0.3?

Thanks,

No, according to RIPE Atlas probes:

Thanks Rob…

Albeit intermittent, I am still seeing timeouts when trying to reach this host. Admittedly, it may be a transit / routing issue via BGP neighbor 3356. Yet, I’m not seeing any other layer 2 anomalies. I’m still investigating. I may tear down the peer and see if the behavior persists…

Thanks again…
