Your platform is the one dependency you cannot route around: when it is down, everything is down. Over the 180 days ending July 2026, Shopify and BigCommerce both recorded zero major or critical incidents (100% uptime, A+). Squarespace posted 99.08% (B), the weakest platform score in StatusBird's dataset, with 2 major incidents totaling 1,548 minutes, nearly 26 hours of downtime.
The numbers, side by side
| Metric (180 days ending July 2026) | Shopify | BigCommerce | Squarespace |
|---|---|---|---|
| Uptime (major/critical incidents) | 100% | 100% | 99.08% |
| StatusBird reliability grade | A+ | A+ | B |
| Major or critical incidents | 0 | 0 | 2 |
| Total downtime | 0 minutes | 0 minutes | 1,548 minutes |
How these numbers are measured: StatusBird checks each service's status every 2 minutes, around the clock. The uptime figures below count major and critical incidents over the 180 days ending July 2026; brief degraded periods are tracked but excluded from the uptime math so that chronically noisy status pages do not distort the comparison.

How reliable is Shopify?
Zero major incidents in the window, but that headline needs one honest footnote: Shopify did have shorter degraded periods in June 2026 (June 3 and June 24) that fell below the major-incident threshold yet still disrupted some stores' checkouts. Both are documented in how often does Shopify go down. Live history is on the Shopify reliability page.
How reliable is BigCommerce?
BigCommerce matched Shopify with zero major incidents in the window. Its record over a longer horizon is on the BigCommerce reliability page and in is BigCommerce reliable.
How reliable is Squarespace?
Two major incidents totaling nearly 26 hours is a substantial amount of downtime for a commerce platform. For content sites an outage is an inconvenience; for a store it is a closed front door. Details on the Squarespace reliability page and in is Squarespace reliable.
Does platform reliability mean you can skip monitoring?
No, for two reasons. First, even an A+ platform sits on top of dozens of other services (payments, email, shipping, apps) that fail far more often; shipping was the worst category in StatusBird's 2026 infrastructure report. Second, platform status pages consistently acknowledge incidents after customers feel them, so "the status page is green" and "your store is up" are not the same claim. Independent monitoring covers both gaps.
