Whilst I don't want to see Ppp go, they've had what, 6 days of downtime now? That's unacceptable, as others suggested in cases where timeframes are strict. Suggestions have been made to MJdev, and offers of help were extended previously and ignored.
If they were indeed working on upgrades on the site, they would have been aware it was down, and if not, surely they would still visit it occasionally? (I visit all of my sites a few times a week, and also have automatic reporting when stuff breaks).
Part of me wishes that the domain had never been renewed, it would have been easy to then provide a link to here and other resources, and also a proxy back to the (still running) ppp server.
