I've been using a popular hosting service for years and it has always met my needs. Although I'm not a tech expert, I can tell the difference between a good hosting service and domain provider. My website used to be well-optimized with an average PageSpeed score of more than 80 on various devices. However, I recently noticed that it has become extremely slow, scoring only 8 parrots on mobile devices and 55 on PC.

What's strange is that nothing had been changed on the site; everything was updated and optimized, including the cache, images, HTML, CSS, etc. Despite conducting all optimization processes again, the site continues to load very slowly, which is quite distressing.

Coincidentally (or perhaps it's a conspiracy theory), a caching service suddenly appears on my website, claiming to increase its speed. I can't help but wonder if they deliberately lowered the site's speed to push their services.

Has anyone experienced something similar before?

The hosting provider is doing its best to survive. Those who require a more stable and consistent resource have been utilizing VDS for a while.

A VDS with 4 cores, 4 GB RAM, and 50 GB SSD capacity only costs $8 per month. By configuring VestaCP in nginx + php-fpm mode (if you can avoid Apache), you can be blown away by the speed difference.

Furthermore, even with a small load, you can host several dozen websites on VDS. Check out vps.today for information on different hosting providers.

On the downside, you must configure everything yourself.

There are many uncertainties to consider. It's highly probable that you are using shared web hosting, which means you're relying on other users who share the resources of a single server. It's possible that one of your "neighbors" could be overloading the server and affecting the performance of your own websites.

As mentioned earlier, it's also possible that your sites were optimized for outdated algorithms, although they have been updated according to Google Page Speed Insights. To solve this issue, it is important to analyze every point that has turned red. However, this is a complicated task that requires a detailed examination.

Selecting the ideal hosting service for your website demands you know where you are hosting and how much you pay for it. If your website traffic increases and your hosting service can't handle the workload, it can lead to a slowdown or non-functionality of your website.

While they have served you well in the past, the hosting landscape is constantly evolving, and changes within their infrastructure or service offerings can significantly impact the performance of your website. I would recommend reaching out to your hosting provider's support team and requesting a comprehensive analysis of your website's resource utilization and any potential bottlenecks they may have identified.

During this conversation, be sure to gather detailed information about any recent changes or updates made to their servers, network topology, or resource allocation policies. Additionally, ask them to provide you with performance metrics and historical data for your website, as this can help identify any patterns or anomalies that may have contributed to the slowdown.

Regarding the caching service that suddenly appeared on your website, I would be extremely cautious and suspicious of its origins and intentions. While caching can be a powerful tool for improving website performance, the sudden and unauthorized appearance of such a service raises significant concerns.

It's possible that this could be a case of a malicious actor attempting to exploit your website for their own gain, either through unauthorized access or by deliberately introducing performance issues to promote their own solution. I would strongly advise you to thoroughly investigate the source and legitimacy of this caching service before enabling it or providing any access to your website.

Consult with a reputable web security expert or your own IT team to ensure that this service is not compromising the integrity of your website or your users' data. Perform a deep dive into the service's code, infrastructure, and any potential vulnerabilities that could be exploited.

In terms of your own optimization efforts, it's essential to take a comprehensive approach to identifying and addressing any potential performance bottlenecks. Begin by conducting a thorough website audit using tools like PageSpeed Insights, WebPageTest, and Lighthouse. These tools can provide valuable insights into the specific areas of your website that require optimization, such as image and asset delivery, minification and compression of HTML, CSS, and JavaScript, and proper configuration of caching and content delivery.

Additionally, consider analyzing the performance impact of any third-party scripts, plugins, or content that may be loading slowly or inefficiently. Identify and address any server-side issues, such as database queries or application logic that could be causing delays.
Website performance is a multifaceted challenge that often requires a deep understanding of various technical disciplines, including web development, server infrastructure, content delivery, and performance optimization. If the issues persist or you encounter any roadblocks, don't hesitate to seek the assistance of experienced web performance experts who can provide targeted guidance and support.
