About Loading Issue in Gtmetrix

Hello

In gtmetrix speed test tool, In Waterfall section, I notice fontawesome min CSS load from maxCDN.

I used maxCDN few month ago but right now do not use it. Instead maxcdn currently I'm using Cloudflare CDN.

I see this file kill my speed little bit.

Is this file currently necessary for my site?

If not, How Can I remove this?

Thanks
