Users of the Gmail to Evernote script may have received a “Summary of failures” message today reporting the following error:
Address unavailable: http://gs.harryonline.net/gm2en.json (line 180, file "Code")
The server, from which this file is read, has been down for a number of hours yesterday, so you got these error messages.
Why is the script reading this file, it is only supposed to forward messages from your Gmail account to Evernote? It has to do with version information, to be able to inform you about new versions.
