Site slowdowns due to large files and content

Sites with large files and content will undoubtedly slow down and affect performance. A CDN uses compression, caching, and content optimization to reduce file size and bandwidth usage in order to reverse the negative effect on your site’s performance.

Out-of-date content

Incorrect content can cause confusion and be a detriment to potential customers. Advanced caching techniques and policies, such as Cache Purge by CDN, will ensure that dynamic contents are kept up-to-date and fresh.

Prevent downtime
