I was recently reminded of the Data Replication Time Calculator I wrote with PK… and thankfully, the guy who reminded me of it found a copy on the Internet Archive. When DroppedPackets.org was converted from Zope to WordPress, the copy I’d posted there was lost. So, thanks to David D it’s now back on the interwebs, on my public Dropbox. Note that this spreadsheet predates the existence of Gigabit Ethernet and Jumbo Frames, which will throw it off in a probably major way.
