Event Streams US East gets dedicated regional IP

<p>On <b>September 15, 2026</b>, Twilio is introducing a new regional IP address for Event Streams webhook traffic in US East (us-east-1). This is part of a move from a single shared IP range to dedicated regional addresses, bringing Event Streams in line with how the rest of the Twilio platform routes traffic.</p> <p>This change only affects customers who validate incoming Event Streams webhook traffic by source IP address. If a setup doesn’t check the source IP, no action is needed.</p>
