Internet speeds do not match my plan.

Hello! 

Ive run into a recent issue of my internet speeds not matching my plan. I currently pay for 1100 Mbps speed, all recent speed tests i've run have have shown somewhere around 5-20 Mbps on various testing websites. My area has had some recent weather events (storms) that i thought may be part of problem. I've tried multiple different things to try to solve this, turn off and on again, upgraded hardware, tested multiple different devices but im at a loss. Im reaching out here to get anymore advice or any other thing i could try,  or if i should try to get a technician visit scheduled? If there is any other info i can provide i would be happy to do so!  

Thank you!!
