China Mobile and Facebook in joint project to build 2Africa submarine cable
thumbnail

The 2Africa project is part of a joint enterprise by China Mobile International, Facebook, MTN GlobalConnect, Orange, stc, Telecom Egypt, Vodafone, and the West Indian Ocean Cable Company (WIOCC).

The 37,000km-long 2Africa cable will feature around 21 landing points in 16 African countries and will carry three times the total network capacity of all the submarine cables currently serving the continent.

Egypt Telecom appears to also be involved in another subsea cable encircling Africa. I don't know if/how it relates or interconnects to the 2Africa cable.

The Miracle Sudoku

In a word, thrilling. When is the last time you heard someone describe Sudoku in that way?

Steps to take to avoid leaking browsing history to third parties

  • Telecommunications metadata
    Your ISP learns every website you visit via a few different channels: DNS lookups, the IP address of sites, and TLS Server Name Indication (SNI). Most ISPs log and store this metadata for some time. Mitigation There's no need to use your ISP's DNS server. Run your own. You can't really getting around your ISP learning the IP addresses you visit. But with TLS encryption and the pervasive use of content distribution networks (CDN) by many website providers, the IP address itself does not really say much. The "leaking" of domain names via SNI is harder to get around, but newer versions of TLS improve on the situation.

  • Web Site Data
    Any Web site that you go to is very likely to keep extensive logs of everything you do on the site, including what pages you visit and what links you click. They may also record what outgoing links you click. For example, Google Search does this. Mitigation Try to use alternative services, that don't track you. Such as Nitter instead of Twitter, Invidious instead of Youtube, DuckDuckGo instead of Google Search, Bibliogram or PixelFed instead of Instagram, Jitsi instead of Zoom, Signal instead of WhatsApp, and so on.

  • Browser Sync Data
    Although the browsing history stored on your computer may not be directly accessible, many browsers offer a “sync” feature which lets you share history, bookmarks, passwords, etc. between browser instances (such as between your phone and your laptop). This information has to be stored on a server somewhere and so is potentially accessible. Mitigation Make sure that whoever hosts this server allows you to properly encrypt your data (in such a way that the server owner can never decrypt). Or even better, self-host the sync server yourself (Firefox sync can be self-hosted in this manner).
