As of today, last year, Russia started its military operation in Ukraine.
Today, in collaboration with Roskomsvoboda, we published a new report documenting how Internet censorship changed in #Russia over the last year based on OONI data analysis.
https://ooni.org/post/2023-russia-a-year-after-the-conflict/
Overall, OONI data analysis shows the blocking of 494 domains in #Russia.
The blocked domains fall under 28 categories, suggesting pervasive levels of internet censorship in Russia.
Many more websites are also blocked, beyond those tested.

New blocks that emerged in #Russia over the last year include:
• Blocking of Russian & international human rights websites (Human Rights Watch, Amnesty International)
• Blocking of investigative journalism & news media sites
• Blocking of Instagram, SoundCloud , Patreon
Access to the @torproject's website was temporarily unblocked in #Russia between 15th to 28th July 2022.
Several discontinued sites have been unblocked over the last year (possibly as part of a “blocklist cleanup”).
We confirmed the blocking of 48 domains (including a @letsencrypt@tweets.icu domain) based on OONI data, which do not appear to be included in #Russia’s official blocking registry.
OONI data also suggests that access to a major CDN was blocked in the past year.
You can continue to monitor internet censorship in #Russia through real-time OONI data:
We thank OONI Probe users in Russia for contributing measurements. 
@ooni Do you happen to know where Russian websites get their TLS certificates from if Let's Encrypt is blocked? Is there another provider of free certificates that is not blocked in Russia?
@chpietsch @ooni we only saw the block of the OCSP service of letsencrypt on one ISP and in a small sample of measurements. It might have been a temporary misconfiguration on the part of the ISP and not an intentional block.
@chpietsch @hellais @ooni would OCSP blocking interfere with sites configured for HSTS, or would local cached results be used?
I don't know. As far as I know. OCSP is not used by all browsers. Its unavailability should not really break anything.
zerossl offers acme support. not sure if they're used in russia though
@chpietsch @ooni it doesn't seem to be blocked here though, not sure why that cropped up but haven't noticed any issues getting letsencrypt certs as of recent

@miv2nir hi! thanks for the notice! The accessibility of the service also depends on the network you are using, we confirmed only the blocking of a Let’s Encrypt domain (ocsp.int-x3.letsencrypt.org) on one specific network (AS44094)
@ooni @letsencrypt@tweets.icu can't prove the blockage of the letsencrypt.org as of right now since im from russia myself, hosting a handful of services utilizing the letsencrypt certs and the domain is accessible from my location 
@ooni please make image descriptions for visually impaired people!
@Sonstwer Thank you, we just added the descriptions to all the charts!
