[Tyler Durden]

Hi

I just added the DownloadExtraInfo in the config file for the nodes
"chulak" and "aurora".



Greetings

> Here is a list of changes to the file format:
> * the "weight" line has been removed, and replaced with a Tor config
>   default (#24679, #24681)
> * the comma that separates fallback C strings is now on its own line
> * a "nickname" comment has been added (#24600)
> * an optional "extrainfo" comment has been added (#22759)
> 
> The added fields will be populated with placeholders until the list is
> rebuilt (#22271). This will hopefully happen some time in the next few
> weeks.

> There are only a few fallbacks that cache extra-info documents.
> I checked 67, and only 4 cached extra-info documents.
