I'm not saying one should convert every single IX peering into a PNI, as I feel both are pretty much required: your smallest peers shall be secured on as many IXes as possible, your biggest ones via PNI. IX peering is mandatory to keep internet routing diversity up to par - and enable small ASes to grow.

The converse can also be true - we have a number of members who use the IX fabric as a backup to their PIs with larger peering partners. If you lose a PI carrying a GE of traffic, where does that traffic go? -- Will Hargrave will@lonap.net Technical Director LONAP Ltd
