About Hank Preston
Hank has spent time in most areas of IT services, but is glad to have his feet firmly planted in sane and predictable world of pushing packets these days. Having the rapid fire attention span common to IT, he dabbles in many network technologies, bouncing from Data Center, to wireless, then security, and ending on core route/switch around dinner time. You can find Hank on Twitter and Google Plus.
All views, thoughts, opinions, etc are those of Hank, and Hank alone.
