- For Europe, US and Canada the Christmas/New Year season (end November thru 2nd week in January) may also be expected to change behaviors, so comparing with data before the first cases (Nov-Jan) may be tricky.
- The measurements are from SLAC which shut down on March 17th, 2020, so the traffic on its links may have dramatically decreased after that.
- Utilization across networks and services has changed dramatically in terms of volumes, number of connections, utilization of links, interfaces, service endpoints. Most services are scaling up to handle the load. There are also many outages due to misconfiguration as people are trying to configure with configurations in production.
- The links from SLAC use the well-provisioned ESnet network and beyond that academic networks such as Internet2 in the US, GEANT in Europe, APAN in Asia, thus the measurements from SLAC may not be fully representative.
- Africa might be interesting since its networks tend to be less over-provisioned than those elsewhere. Also, see https://www.npr.org/sections/coronavirus-live-updates/2020/04/17/836896562/u-n-agency-fears-vulnerable-africa-may-suffer-at-least-300-000-covid-19-deaths
- Another possibility is South and Central America and the Carribean.

- Many of the targets are academic establishments that may have been closed, thus the target itself may be lightly loaded and so respond more quickly than in the past.
