Iodine

⚠️ Highly technical. Requires real networking skill to set up. Not beginner-friendly.

Iodine is a tool that can sneak your internet traffic past certain kinds of blocks. During SOME shutdowns, authorities don't switch off the network completely. They leave a few small background channels open, because phones and computers need them just to function. Iodine hides your internet traffic inside one of those still-open channels, letting it slip past the block. The channel it uses is called DNS, the system that looks up website names, which is often left working even when normal internet is cut off.

Metadata Removal

Metadata is “data about data” - information that describes or gives context about a file, without being part of its main content. For example, date and time a photo was taken, location where a photo or video was taken, etc.

VPN

There are multiple VPNs on the market, and we have not included all of them. Our standard criteria include providers that meet at least some of the following: open source, strong encryption, independent security audits, a no-logs policy, a track record of supporting human rights, and not being owned by data mining companies. However, each VPN operates differently with various protocols. We recommend ensuring it works in your region.

Using VPNs may be illegal in some countries. VPNs require a small amount of data to connect, making them ineffective during a full shutdown but potentially useful during throttling.
