I hear your concerns, and have a proposal how to quantify this concern:
- First, amend the page to say that all the data are public. (Possibly
also switch the flag, but that can be a separate step.)
- Second, observe what has changed in the usage pattern.
- Third, evaluate.
That way we don't need to stay in limbo over hypothetical situations but
get real data.
Side note about usefulness of one-off measurement history:
I think it _might_ be is interesting for anyone doing study on any given
outage, or even study about optimization practices over time.
For example, the DNS community has service called DNSViz which does just
one-off measurements, and yet, researchers come and write papers based
on data from DNSViz.
HTH.

Dear colleagues,
The quarterly plans for RIPE Atlas can now be found at:
https://www.ripe.net/support/documentation/quarterly-planning/ripe-atlas
In the last quarter, we worked on several proposals to change the RIPE
Atlas behaviour, including implementing general availability of HTTP
measurements and removing the ability to schedule ?non-public?
measurements.
This quarter, we?ll continue with the distribution of the v5 RIPE Atlas
hardware probes to hosts, ambassadors and sponsors as well as work on
other items proposed by the community.
If you have any input on our plans or want to let us know what you would
like to see us work on, please let us know.
Kind regards,
Robert Kisteleki

What would you propose the API to do if this rule is violated? Should it
outright refuse the measurement, or should it silently turn on the
public flag (silently, because even if we emit a warning, it is probably
never seen by a human...)?

I guess this hinges on what level of support (legal, technical or other)
we're aiming for when it comes to others building services on top of
RIPE Atlas.
Regards,
Robert

I think the safest thing would be to refuse with an error message. Just
override a setting with just a warning is probably not enough, as you wrote.

I really love RIPE Atlas and all the possibilities that come with an
open and mature platform. I think as much as possible should be open and
reusable by others. However, I understand that some people in some cases
have other wishes.

Dear Robert,
As I have expressed at other times, I think we have to be very careful
with enabling HTTP probes due to traffic increase issues.
I have personally delivered quite a few probes to remote locations
in regions with very poor connectivity, and the host's first concern
is how much bandwidth the measurements take up. I have always reassured
them that these are only network level connectivity measurements, and
no web traffic. It seems to me that in the first world it may be
difficult to imagine places where a few megabytes per month of traffic
matters, but that is the case in remote regions, and I think the
benefit of having an Atlas network with worldwide coverage is greater
than being able to perform higher layer measurements or monitoring.
It seems to me that the idea of making it "opt-in" with a tag on the
probe is the right one, even if it makes its deployment and usability
slow at first. I sincerely believe we have a responsibility to hosts
that currently help in complex regions.
Thanks and regards,
Hugo Salgado

Dear colleagues,
The new version of the RIPE Atlas streaming API is now available.
As mentioned in the previous e-mail, the API can now be accessed using
either plain WebSockets or plain GET requests.
Socket.IO support is being maintained for now, so you don't have to
immediately change your installations, but the new interfaces should be
preferred wherever possible.
The documentation can be found at:
https://atlas.ripe.net/docs/apis/streaming-api/
Kind regards,

(In the Cons) "Possible arguments about which provider to include in
this set and which to refuse."
There is a larger problem here, a more strategic one: such a feature
would contribute to the centralisation of the Internet, which is
already too important. Tagging some targets are "important" and
"worthy of measurements" would mean that we consider some HTTP servers
to be more useful than others. That would be a bad message from RIPE.
