10. Winlink 2000 Today by the numbers Over 99% system availability since Nov, 1999. 5 Full-time, Redundant, Mirror image, Common Message Servers (CMS) in Halifax, San Diego, Washington DC, Perth, and Vienna all in hardened sites, providing excellent reliability, worldwide. (Wash DC is DHS sponsored, Halifax is Canadian Sponsored) 600+ total Radio Message Servers, worldwide, in 3 major Service Classes: Public, EmComm, Amateur, and Government (MARS controlled) maintaining separate operations. Approximately 13,000 Radio users communicating with over 100,000 Email recipients, pushing an average of 150,000 messages or 280,000 minutes, monthly, with an average duration of 3.4 Minutes at 3,600 bytes/per message. The average time from message origination to availability for delivery is less than 1 minute, regardless of distance. The greatest growth is now in Emergency Communications preparedness. (Not all Amateur Radio)

11. Traditional role of Amateur Radio in ECOM: Support – Incident Command, Search, Report health and welfare of affected public Voice communications among served agencies (EOC's, hospitals, shelters, and incident command.) Site tactical and rescue, damage and storm reporting (SKYWARN). “Formal,” - limited written emergency traffic handling – RTTY at best.

12. Why Winlink? Our traditional methods fail to meet needs for complex message handling in today’s agency environment! Since the advent of e-mail: –Need for delivering written procedures, lists, graphics, images, and Pre-defined, formatted, documents to multiple recipients! –Multiple recipient e-mail with binary attachments is the de facto standard to carry written information. –Hand-written message forms are seldom used, and are not transparent to normal operations! For complex messages, voice, Morse code, Radiograms, and traditional Packet radio won’t do… –Way too slow, translation required, inflexible, prone to error, no permanent record, not self-originating, not point-to- multipoint. –Doesn’t go end-to-end from user-to-user on their own computers in their own offices & no attachments and no automatic distribution..
