WebSitePulse 2021 Hurricane Season Web Performance Report Summary

Finally, the hurricane season 2021 has ended, and it was not a quiet one. It had fewer storms/hurricanes and deaths than the 2020 season, but the damages in 2021 are significantly more.

In 2021 in the Atlantic basin, we observed:
  • 13 Tropical storms (Ana, Bill, Claudette, Danny, Fred, Kate, Julian, Mindy, Odette, Peter, Rose, Victor, and Wanda)
  • 1 Subtropical storm (Teresa)
  • 3 Category 1 hurricanes (Elsa, Henri, and Nicholas)
  • 2 Category 3 hurricanes (Grace and Larry)
  • 2 Category 4 hurricanes (Ida and Sam)
The total damage from the Atlantic storms is more than $70.5 billion and 103 deaths.

The storms in the Pacific basin caused significantly less damage (total under 200 million and 46 deaths):
  • 11 Tropical storms (Andres, Blanca, Carlos, Dolores, Guillermo, Jimena, Ignacio, Kevin, Marty, Terry, and Sandra)
  • 4 Category 1 hurricanes (Enrique, Hilda, Nora, and Pamela)
  • 2 Category 2 hurricanes (Olaf and Rick)
  • 2 Category 4 hurricanes (Felicia and Linda)
The total damage from the storms in the Pacific base is more than $235 million and 13 deaths.

Along with the end of the 2021 Hurricane Season, we have finished tracking five of the most popular weather forecasts websites for our annual Hurricane Season Report.

For this Performance Report, we at WebSitePulse monitoring service measured the websites' home pages' performance and complete interaction with the website as an end-user would do.

The report measures Uptime and Response Time as the most critical metrics for all web-based operations' availability and reliability. Measurements of the multi-step online transactions were made every 15 minutes, simultaneously from 3 different monitoring locations: Trumbull, CT (US East Coast), San Francisco, CA (US West Coast), and Chicago, IL (US Central).

The overall uptime and speed of the monitored weather websites were quite good during the whole monitored period. We have found out the daily average response time from all monitored websites was 0.659 sec. The daily average responses by locations are as follow:
  • Trumbull, CT (US East Coast) – 0.676 sec
  • San Francisco, CA (US West Coast) – 0.815 sec
  • Chicago, IL (US Central) – 0.490 sec
For the fifth year in a row, The National Hurricane Center (nhc.noaa.gov) was the speed leader among the five monitored websites with an average response time of 0.438 seconds, followed by redcross.org (0.469 sec). A the bottom of the table was floridadisaster.org with 0.901 seconds average response time, which may have frustrated some of its visitors.

Compared to the last year's performance, the two leaders increased their response time by an average of 0.096 seconds, while the slowest site this year performed on average 0.158 seconds faster than in the 2020 Hurricane Season monitored period.

The daily average uptime for the entire group of 5 websites for the 2021 hurricane season was 99.99%. The daily average uptime by location are as follow:
  • Trumbull, CT (US East Coast) – 99.99%
  • San Francisco, CA (US West Coast) – 99.99%
  • Chicago, IL (US Central) – 100%
We have only one winner this year — weather.com, which was available with no interruptions, closely followed by redcross.org with 99.999% uptime. At the bottom of the availability chart once again stands salvationarmy.org with 99.982%, which means it was not accessible to its visitors for almost 25 minutes during the monitored period.

Report Methodology:
WebSitePulse Performance Reports measure Uptime and Response Time as the most important metrics for the availability and the reliability of any web-based operation. Performance measurement took place daily, every 15 minutes during the entire Hurricane season, between the hours of 6AM and 3AM EST. The WebSitePulse website monitoring service was used to collect data and to create the reports.
The simultaneous monitoring is performed from 3 US locations of the WebSitePulse monitoring network: Trumbull, CT, San Francisco, CA and Chicago, IL. In case of a detected malfunction or unavailability, the system performs automated error verification from 3 independent resources and only after the above procedure is performed and has returned consistent results, the detected error is confirmed, recorded, and included in the daily performance reports. In these cases, an advanced WebSitePulse exclusive feature comes into play - Forced Monitoring - which automatically switches to a 3 minute - monitoring interval for increased accuracy.

About WebSitePulse:
WebSitePulse is a leading provider of global, independent, and objective availability and performance monitoring of web sites, servers, network components, web applications, e-business- and email round-trip transactions.

WebSitePulse launched the Performance and Uptime Reports program to keep the general public and the Internet community informed about the performance of specific websites and the challenges their webmasters, owners and operators are facing on a daily basis, especially when the web traffic intensifies due to some special events through the year. Some of the most popular web destinations, related to each particular event, are selected for the purpose of the Reports, and data from their performance measurements is made available on the WebSitePulse public website.
