I ended up writing a flask app that parses provider maintenance emails and posts slack notifications at the start and end of the window. You can also extend it to take actions like drain/undrain traffic during windows. Right now the five supported providers are NTT, PacketFabric, EUNetworks, GTT, and Zayo. The first three follow the MAINTNOTE standard. The last two were done via bs4 and good old regex. Upcoming parsers are in the works for Reliance, CenturyLink, and Tata.

I hope others find this useful and deploy it for their networks. Let me know what you think and if you'd like to contribute: https://github.com/wasabi222/janitor

Here are some screencaps: https://imgur.com/a/tMTlMwH

If you know of more providers that follow the MAINTNOTE standard, please let me know so I can add them to the parser. Thanks!

Back at NANOG in Chicago 2016 someone was working on a standards for Maintenance notifications with calendar invites attached. Not sure what happened with it.

I think this was it.

Is there commercial or open source software that already has this implemented?
