Global Internet Infrastructure (that stability thing….)
What is it? • First thing I asked myself when I was asked to talk on this subject was… “What exactly is “Global Internet Infrastructure”?” • If in doubt make up a new Acronym…. • LMGTFY
http://www.lmgtfy.com/?q=Global+Internet+Infrastructure • Funnily enough… • When people talk about the “Global Internet Infrastructure” the “Internet” is itself the most global of Infrastructures. • “The Internet is truly a global infrastructure for the 21st century -- the first really new infrastructure to develop in nearly a century” V. Cerf 1995
The Internet is probably the most important communications enabler that has been invented since the telegraph. • Global Instability in that system would have very dramatic effects…
Data on Stability of Internet • Finding measurement of this is not as easy as you would think • Firstly we don’t have a good definition of what this “Stability” means. • Secondly there have been very few scientific publications on the matter in the last 10 years LMGTFY……
Recent major outages • Issues with physical infrastructure…. • Data centers disappearing, fiber cuts etc.. • Issues with identifier systems.. • Names, IP addresses (routing) etc…
Earthquakes, Storms and…. • 2006 Taiwan Earthquake • A cable break • Natural causes • The damage was serious locally • New on this Internet outage could be followed on the Internet… (unless you were in Taiwan)
2008 Fiber cuts… • 5 (or was it 3 or 9?) undersea cables were accidently damaged. (reported to be by ship anchors) • This caused outages for millions of people. • You could follow the minute by minute updates of this on the …. Erm…. Internet.. • It was a major outage but it’s affect was Local.
2010 Haiti Earthquake • Cables were damaged.. • This caused some communications issues inside and with Haiti. • My own communication with those inside Haiti was mainly conducted using the Internet... • For those going to IGF come see the .HT talk on this at the CENTR panel.
The identifier systems • These may be expected to be more global in reach as the protocols are globally deployed.
2002 Attack on Root servers. • Great headlines “Massive DDoS Attack Hit DNS Root Servers!” • Was followed and reported widely on the Internet. • In reality everything kept working..
2007 Attack against Root Servers • Very large attack… affected a few of the root server systems • Reported heavily on the …erm.. Internet • Everything kept working….
2010 RIPE NCC experiment • Triggered a bug in Cisco IOS code (Routers) • Reported (on the Internet) to have affected about 1% of “Internet” • http://www.networkworld.com/community/blog/cisco-bug-behind-small-scale-internet-outage?source=nww_rss • Very short term outage.. Did cause some short term discomfort
Although the Internet is “Global Infrastructure” the way it is designed and implemented means that “outages” or “instability” is localized. • In the history of the Internet it is hard to find one example of a truly global outage. • Local outages happen all the time… • You can read about them on the Internet!
We should not be complacent…. • The fact that we discuss and act on such issues at length and that a lot of actions have taken place to improve stability and resiliency is testimony to the fact that as industry we are not… • but so far we have done a pretty good job…
