Uptime This Week

Carwow maintained perfect availability at 100% uptime throughout the week, while AutoTrader recorded 0% uptime, indicating the service was unreachable during the entire monitoring period. This stark contrast suggests AutoTrader experienced a sustained infrastructure failure or outage affecting all monitored endpoints. Uptrue's continuous monitoring detected no recovery windows for AutoTrader during this seven-day interval.

Response Time

Carwow responded to requests with a 124ms average latency, consistent with typical performance for hosted e-commerce platforms. AutoTrader's response time could not be measured due to complete unavailability during the monitoring period.

Incidents & Downtime

Neither provider recorded any successfully-captured incident events in Uptrue's monitoring logs during this period. However, AutoTrader's 0% uptime classification indicates a continuous failure state rather than discrete incidents—suggesting infrastructure-level issues rather than transient problems.

Historical Context

UK automotive marketplaces typically operate with 99%+ uptime targets due to the high-value nature of transactions and user expectations. Complete or near-complete unavailability events, while rare, can result from database failures, CDN misconfigurations, or DNS propagation issues affecting the entire service tier.

Which Should You Choose?

For transaction-critical automotive marketplace use cases, Carwow demonstrates reliable availability during this monitoring period. AutoTrader should not be relied upon without investigation into the root cause of the reported 0% uptime—this may reflect a monitoring configuration issue, DNS resolution failure, or genuine infrastructure failure that requires vendor communication and verification.
