In case anyone's looking here for an update...
Latest from VoIP.ms's Twitter was at 4:30pm (EDT) yesterday (~26 hours ago).
VoIP.ms's web site is usually up. Behind heavy CloudFlare protection.
At least at $Day_Job, VoIP.ms phone service continues to be ~100% down.
No updates I could find from a few quick Googles, but a Belgian ISP is being DDoS's with a vaguely similar timeframe (dunno if VoIP.ms has any connection to them) - https://news.ycombinator.com/item?id=28578399
