TeknoDragon's Journal: Commercial Rate ISP's: Know your Service Level Agreement!

Notes for a new topic:

know your SLA, most of them suck

99% uptime = 15 min outage total per day
99.9% uptime = a good benchmark for the standard
everyone should offer at least 3 'nines'

latency: use traceroute and pathping! most places garuntee a level of latency within their network, better ones should garuntee latency within their top-tier upstream/peers

maximum latency: at what level is a latent packet considered dead for uptime?

monitoring tools:
what ones exist? how to diagnose packet loss? how to diagnose latency? device specific links...

"you can't diagnose it with ping: ICMP is routed last"
don't fall for this bullshit, ICMP may arrive late but if your network is congested or has problems then your pings will have issues too!
