Is auth.simperium.com still supported?

  I ask because api.simperium.com and simperium.com both respond normally, but auth.simperium.com times out on HTTPS:

  • auth.simperium.com resolves to 192.0.84.248
  • ping auth.simperium.com succeeds
  • tracert auth.simperium.com reaches Automattic’s network
  • curl.exe -I https://auth.simperium.com times out connecting to port 443
  • Browser also times out
  • Tested on both home Internet and a mobile hotspot

  This appears to affect clients that rely on Simperium auth. Is this endpoint retired, temporarily down, or replaced by a newer Simplenote authentication flow?

  For reference, Simplenote Web, the official Simplenote Windows app, and nvPY work for me, while ResophNotes and AlephNote do not.

  Throwing in a comment that I hope auth.simperium.com is fixed, since I use ResophNotes which attempts to sync through this. :)
