As of 24th November 2023, OONI data suggests that some ISPs in Guinea started blocking access to WhatsApp, Telegram, Facebook, Twitter, Instagram, and YouTube. The blocks appear to be implemented by means of TLS interference, and the most recent data suggests that they're ongoing.

OONI data:

The blocking of YouTube is further suggested by Google traffic data, which shows a drop in YouTube traffic originating from Guinea over the last days: https://transparencyreport.google.com/traffic/overview?hl=en&fraction_traffic=start:1698710400000;end:1701129599999;product:21;region:GN&lu=fraction_traffic
