Earthquake in California Impacts Internet Performance
Minimally, Reports Keynote
The large scale earthquake in Central California appeared
to have little impact on Internet performance in
the minutes following the rumbler.
The strong earthquake occurred at 11:15 AM (PST) on
Monday, December 22, 2003 and had a magnitude 6.5 on
the Richter scale. According to the USGS, the epicenter
was located NE of San Simeon, CA with a hypocentral
depth of 8 km (5 miles).
Based on Keynote's initial assessment, major sites
with related quake info or overall news fared well.
The USGS official update site http://quake.wr.usgs.gov/recenteqs/Quakes/nc40148755.html had a varied response from sub-second download times
from the San Francisco, Chicago and Dallas to over
45 seconds from New York and Boston. Keynote's overall
gauge of Internet performance, the Internet Health
Report (www.internethealthreport.com) showed latency
between the major Tier 1 backbones to be well within
the Healthy to Stable region (80ms to 120ms).
Major news sites such as cnn.com, msnbc.com and foxnews.com
were quick to place bulletins on their site alerting
visitors about this morning's earthquake. The sites
remained resilient as the home pages downloaded in
less than 10 seconds (as measured from multiple cities
around the United States), as many affected residents,
and others, flocked to the sites to obtain up-to-the-minute
information about the quake.
