Apple keynote launch sync, September iPhone reveal → catalog + pre-order flow?

Apple keynote drops at 18:00 UTC (10:00 PT) the second Tuesday of September. Pre-orders open that Friday at 12:00 UTC. By 19:00 UTC keynote day your site needs:

• iPhone-17-Pro / Pro-Max SKUs flipped visible, cron-scheduled category visibility. Pre-seed the SKUs in admin during the summer (after Apple’s WWDC leaks confirm model names + dimensions); set them to visibility=hidden until the cron flips at 19:00 UTC on keynote day.
• Pre-order queue live, backorder mode + payment-vault tokenization. Stripe/Adyen tokenizes the card but doesn’t charge until stock arrives. Magento backorders attribute on the SKU.
• MFi cert pending banner, new device dimensions mean new MFi cert applications. Banner says “MFi certification pending, ships when Apple-approved (typically Oct).” Sets expectations.
• Email + SMS to waitlist, cron triggers Klaviyo / Attentive campaign at 19:01 UTC. Waitlist signups from previous quarter get first-look.
• Cloudflare/Akamai cache purge, same cron purges homepage + category pages so the new SKUs render instantly.

Traffic spike: 4-8x baseline for the next 48 hours. Pre-warm Hyvä cache 30 min before keynote, run a war-room on Slack, have a manual cron-trigger fallback ready. I’ve shipped 5 of these keynote launches without double-sells. Without the prep, the typical failure mode is “customer cards, stock arrives 3 weeks late, double-charge, refunds + angry tweets.”
