Verified that our hosting provider is operational

I run a security company in London that provides security guards and related services. Our website is crucial for attracting new clients, handling inquiries, and showcasing our services. However, we’ve recently noticed that the site has become very slow to load and, at times, completely unresponsive. At first, I thought it was a temporary issue, but it has persisted for several days. Some visitors have reported that the website takes too long to load, while others say they receive error messages or SSL warnings. Since our business relies on the website for leads and customer engagement, this is a serious concern. What I Have Checked So Far: Verified that our hosting provider is operational Cleared the website cache and restarted the server Scanned for malware or security breaches Checked that our SSL certificate is valid Tested the website on different devices and networks I’m unsure whether this is due to server problems, high traffic, a DDoS attack, or a misconfiguration in our website settings. Has anyone experienced something similar? Could this be a DNS issue, firewall restriction, or a hosting-related problem? Any troubleshooting advice or solutions would be greatly appreciated! Thanks in advance for your help! [https://gmsecurityservices.co.uk/ https://gmsecurityservices.co.uk/]
