Monitor the DNS resolution.
Check if the main domain DNS and the sub domains referenced by your main site resolves properly around the world. A DNS maps your domain name to its corresponding IP address and directs you to the intended website. The improper working of a DNS server will lead to slower loading of your website.
Periodically inspect the CDN's.
If you have a Content Delivery Network (CDN) set up, make sure there are no nodes in the chain that are behaving differently. In a CDN, the pages of the website are copied to a network of servers distributed across different geographical locations. To access these pages a request is first initiated. The CDN directs the request to a server that is geographically nearer to the origin of the request. This ensures that the time taken to retrieve web pages is reduced.
Keep the throughput in check.
The processing done by a system in unit time is called the throughput of that system. Check if all sub-domains give you acceptable throughput, i.e, an optimal processing speed. If you have lots of content to be downloaded, the throughput of your server should not be the bottleneck.
Make your website mobile friendly.
Google started rolling out its mobile friendly algorithm update on April 21, 2015, which boosts mobile search rankings for websites that are mobile friendly. Test if the mobile site for your website works as expected. This will result in a better SEO.

Collect downtime reports.
Ensure your IT Team has sufficient data to troubleshoot if there is an outage. Ping stats, DNS reports, trace route results, digg reports, root server output are some of the most needed immediate results. Track best practices by adding notes to outages in the web client.
Configure your server to recover immediately.
Set up agents on the web server to restart a process on the server from the convenience of a mobile device so that you keep the Mean Time Taken to Repair (MTTR) very low.
Monitor your website from multiple locations.
