Presslabs has been a regular for many years on these benchmarks and this is the first time they didn't earn Top Tier marks that I can recall. Presslabs had excellent load tests, they were third fastest in WPT response times. The only problem was SSL renewal didn't go smoothly and caused some downtime which dropped them below 99.9% which is required to earn any awards. Overall, a solid product that continues to handle the tests well with one costly mistake this year.
Presslabs has historically done very well in these tests. Presslabs put up excellent Load Test results in both Load Storm and K6. They were error free and excellent. The only thing that held this otherwise Top Tier performance back was an SSL certificate renewal issue which caused uptime to drop below the 99.9% level required to earn Top Tier status.
Presslabs has been a regular at the Enterprise tier and I think this is the first time it didn't win Top Tier recognition. The highlight was probably the fact they were the only company to have 0 errors on both Load Storm and K6. Presslabs had the third fastest WP Bench. It had the fourth fastest WPT average. The only thing that held it back was the same bug across all tiers where the SSL certificate failed to renew properly and caused uptime to drop below the 99.9% threshold. One bug away from a Top Tier performance unfortunately.

This small company has participated many years and continues to impress with yet another Top Tier performance. Perfect uptime. 1 error total on the load tests was the lowest total of any company. The third fastest average response time on WebPageTest. Well done Presslabs.
