Hi Rymus,
Dave here firmly back on the ground! I remember back then last year with the network problems in Carrigaline - pretty stressful times alright for all concerned! Well we got things sorted out there and thankfully things are nice and stable now. We have more capacity and latencies are gone down, so there should be no problems with VOIP. I would like to hear from anyone down there about their experiences for 2007 so far.
Of course, we also monitor the latency and uptime ourselves and I have no problems being open with people about this.
This is our NOC latency graph for Carrigaline for the last month:
As you can see it is about 13ms average from the fibre node - about 10ms off-peak going up to about 18ms average at peak-time. Add about 9ms over the fibre to the internet. These are round-trip times and also you should be looking at the green line, forget about the grey.
So no problems there for VOIP.
Dave
