105+### Updates

107+By default, you will automatically receive updates ([OTAs](@/docs/glossary/ota-updates.md)) from your sponsor. To check your OTA source, run `|ota` in the [dojo](@/docs/glossary/dojo.md).
108+
109+If for some reason (for example, if your sponsor is out of date), you can switch OTA sources by running `|ota ~otasrc %kids` in the dojo, where `~otasrc` is the ship from which you want to receive updates. It is a good idea to contact the source ship and ask permission to sync from them.
110+
111+If OTAs are not succeeding, or if you are on an version of Urbit before the `|ota` command was introduced, you can run `|merge %kids (sein:title our now our) %kids, =gem %that`. **Warning:** this will wipe out any documents in the publish app, as well as any custom code. It will leave chats, links, and group memberships intact.

107115On startup Urbit tries to bind to `localhost:80`. If you're already running something on port `80` -- such as any other HTTP server, or another urbit -- you'll find the urbit that you just started on `8080`, `8081`, and so on. For planets only, we also proxy web domains through Urbit's own servers. Any planet `~your-urbit` is also at `your-urbit.arvo.network`, but only after you [set up DNS](#dns-proxying).
