Black Friday Readiness ,illustration by PFLB
WILMINGTON, DE, UNITED STATES – November 10, 2025 – As online retailers prepare for another record-breaking shopping season, PFLB, a global provider of performance testing solutions, has released a checklist of expert tips to help eCommerce brands maintain site stability and speed during Black Friday and Cyber Monday. Since 2008, the company has helped clients prevent downtime and revenue loss during peak sales events.
Last year’s Black Friday and Cyber Monday brought unprecedented traffic spikes that caused slowdowns and checkout errors for major retailers. PFLB engineers expect even higher loads this season, warning that the window for preparation is quickly closing.
“Every year, we see the same pattern: companies wait too long to test their systems, and they end up scrambling during peak traffic,” said Boris Seleznev, Professional Services Director at PFLB. “Our message to retailers is simple – start testing early, fix bottlenecks now, and make sure your systems can handle real-world user loads before the holiday rush.”
The company’s experts recommend these key steps for ensuring site stability and speed:
PFLB’s Black Friday & Cyber Monday Readiness Checklist
Start early. Begin testing well in advance to identify and fix bottlenecks before the high season. Tools like the PFLB help simulate real user load.
Get expert performance testing help. Don’t stop at identifying issues – understand them. Experts can analyze whether your site can handle increased traffic, pinpoint load-related slowdowns, and verify that front-end elements like images or scripts aren’t adding unnecessary strain.
Avoid peak-hour testing in a prod environment. Running tests during live shopping hours can disrupt customers and transactions.
Prioritize critical areas. If time is short, focus on the most visited pages and simulate maximum load scenarios.
Use reliable tools. Choose proven load testing platforms that provide consistent, transparent results.
Helping Retailers Prevent Downtime Since 2008
For more than 15 years, PFLB has partnered with leading global eCommerce brands to test and optimize site performance under extreme load conditions. From mobile app scalability to cloud infrastructure validation, the company’s solutions help retailers deliver smooth, uninterrupted shopping experiences during major sales.
“Downtime during Black Friday isn’t just a technical issue – it’s a business risk,” added Seleznev. “With the right preparation, performance testing becomes a competitive advantage, ensuring every customer can browse, shop, and check out without frustration.”
To help retailers prepare for peak shopping periods, PFLB offers personalized consultations and rapid performance assessments to ensure every site is ready for high traffic. Brands can get in touch at https://pflb.us/, and a technical account manager will respond within one business day.
