Re: Wanted: volunteers with bandwidth/storage to help save climate data

Simply put… if the data that is hosted on the sites aforementioned then cough up the damn space and host it. Data space 
is cheap as hell these days, parse it and get the hell on with it already.


*Disclaimer*
not meant to single out any one party in this conversation but the whole subject all together. Need someone to help 
mirror the data ? I may or may not be able to assist with that. Provide the space to upload it to and the direction to 
the data you want. But beyond all that. This subject is plainly just off topic.

IMO, *operational, politics-free* discussion of items like these would
also be on topic for NANOG:

- Some *operational* workarounds for country-wide blocking of
Facebook, Whatsapp, and Twitter [1], or Signal [2]

Steering things back towards the operational, the makers of Signal
announced today [1] an update to Signal with a workaround for the
blocking that I noted earlier. Support in iOS is still in beta.

The technique (which was new to me) is called 'domain fronting' [2].
It works by distributing TLS-based components among domains for which
blocking would cause wide-sweeping collateral damage if blocked (such
as Google, Amazon S3, Akamai, etc.), making blocking less attractive.
Since it's TLS, the Signal connections cannot be differentiated from
other services in those domains.

Signal's implementation of domain fronting is currently limited to
countries where the blocking has been observed, but their post says
that they're ramping up to make it available more broadly, and to
automatically enable the feature when non-local phone numbers travel
into areas subject to blocking.

The cited domain-fronting paper [2] was co-authored by David Fifield,
who has worked on nmap and Tor.
