status: Create public status / downtime announcement / bandwidth charts(?) page

[iliana]

It's a start: https://github.com/wobscale/status.wobscale.website

Next steps are:

• Creating an equivalent of "down for everyone or just me" by asking remote servers to check if we're up with JS
• Checking with membership if anybody has concerns about posting bandwidth charts
• Posting bandwidth charts

Additional steps include announcement/notice emails to all interested parties.
