Dear nethistory,
public-webhistory &

Thank you for your "terms of references" (how you use the term "outage" and
information sources deserve to notice).

The "Measuring the Internet" above is part of 2020 Internet Society Action
Plan Projects":

"2020 Action Plan Projects

Let us know which projects you’d like to be involved in!

No matter if you are an individual member, a Chapter/SIG administrator or
an organization member, we would like to hear from you. Follow the
instructions belowand update your profile".
