Hello friends, OONI published two short reports documenting new blocks that emerged over the last few days: * *Guinea blocked Facebook, TikTok, and YouTube:* https://explorer.ooni.org/findings/106140107100 * *Saudi Arabia just blocked Tinder*: https://explorer.ooni.org/findings/305408501600 On 27th July 2026, Guinea started blocking access to social media… again. OONI data shows the blocking of Facebook, TikTok, and YouTube on Orange Guinée (AS37461) by means of TLS interference. Amid ongoing political instability, this follows previous social media blocks in May 2023 and November 2023. Yesterday, Saudi Arabia started blocking access to Tinder. OONI data shows that Tinder is blocked on Mobily (AS35819) by means of TLS interference. We were alerted of this block through our new Censorship Alert System, an internal prototype that we're currently testing and hope to publicly release over the next year. We thank OONI Probe users for contributing measurements! All the best, Maria.
