A Successful Connection Rate is conditioned on (x) Customer utilizing a sufficient number of concurrent connections to support such Successful Connection Rate; (y) Customer’s send requests not exceeding (i) with respect to emails originating from North America or South America, six (6) gigabits per second in the aggregate or (ii) with respect to emails originating outside of North America or South America, four (4) gigabits per second in the aggregate; and (z) Customer honoring Twilio's then-current time-to-live value for domain name system lookups of the Web API v3 Mail send address.
“Total Monthly Time” means the total number of minutes in the applicable calendar month.
“Twilio Services APIs” means the application programming interfaces branded as “Twilio”.
