The outage nobody noticed: PropNex Family Zone

PropNex ran its Family Zone as part of the Picnic & Movie Night with Families for Life at Gardens by the Bay. Over two thousand guests, four hundred families, an outdoor event under direct afternoon sun. The queue moved fast and the day ran smoothly. Then, somewhere in the middle of it, the internet went down. Almost nobody noticed, and that's the part worth writing about.

The outage nobody noticed

Partway through check-in, someone pulled a cable by accident and part of our connectivity dropped. At most events that's the moment the queue stops and the apologies start. Not here. The kiosks caught the drop, failed over to offline mode, and check-in kept going exactly as before. Guests scanned, checked in, the line kept moving. The crew kept working and the guests never knew a thing.

Once we found the pulled cable and plugged it back in, the kiosks flipped back to online and synced every offline check-in to the server. Nothing lost, nothing double-counted. The attendee record was complete and correct, as if the outage had never happened. That's the whole point of offline-first: you plan to lose connectivity, you don't hope to keep it.

Heat is a human problem

The other half of an outdoor event in Singapore is the weather. A registration desk in direct sun is hard on the guests waiting, the crew working, and the tablets themselves. The organiser planned for it and ran overhead fans across the registration area, which cooled the team and kept the queue patient. We kept our own crew hydrated the whole window. If you're planning an outdoor event, budget for shade, fans and water the way you'd budget for the gear. It's what keeps a desk sharp from the first guest to the last.

A managed queue is a fast queue

Two thousand people will form a line. Whether it moves comes down to how you run it. Direct the guests, prep them, keep them flowing, and the wait stays short even at the busiest stretch.

Here's the setup behind it: six self-check-in tablets and a manual laptop, all running on our own cellular network instead of the venue wifi. Check-in only, so pre-registered guests scanned in to collect a goodie bag and vouchers, with no walk-up sign-ups and no badges to print. Outdoors you don't get to assume connectivity, so we bring our own and build the kiosks to keep going when it fails. Two thousand people, direct sun, a pulled cable, and a queue that never stopped. That's what resilient check-in looks like.
