Shopify store loads very slowly on Comcast

[atoneboutique]

Hi Everyone,

As of a few days ago, my Shopify store (https://atoneboutique.com/) takes painfully long to load on Comcast. Sometimes it takes multiple minutes just to load the homepage. I'm fairly certain this is just an issue on Comcast. Shopify support said the site was fast to load for them, it loads very quickly on mobile data, and I've had friends and family confirm that it loads quickly for them on other ISPs.  I'm also fairly certain that it's not just my modem as my internet speed is generally very fast, and this is the only site I'm having trouble with (I'm working from home and online all day and haven't had any issues with any other sites). I've also had friends who use Comcast confirm that the site is slow for them. I've tried restarting my modem, clearing my browser cache/using incognito, accessing via Chrome and Safari on my laptop and Safari on my phone while on WiFi, all with no success. I've deleted all the apps on my Store and confirmed my DNS settings are correct: 23.227.38.65 for Record A and shops.myshopify.com for the CNAME record for my Google Domain. Those are my only DNS settings. Shopify online store speed report says my speed is faster than other similar stores (59), and GTmetrix gives my site a score of A with 97% (https://gtmetrix.com/reports/atoneboutique.com/3lpCVgwy).

Is anyone else experiencing anything like this? I've seen multiple similar posts (https://www.reddit.com/r/ecommerce/comments/904e89/comcast_users_have_been_unable_to_load_shopify/ and https://community.shopify.com/c/Shopify-Discussion/Shopify-Comcast-Failure/td-p/456170 for example), but all are from 2017 or 2018. I haven't been able to find anyone mentioning anything similar recently. Is there anything else I can try, or do I just have to wait until Shopify sorts this out with Comcast? I live in Chicago where a ton of people use Comcast, and I'm planning on having a closet sale with an influencer I work with in a week, so I need my site to function correctly. My site is essentially unusable like this.

I'd appreciate any help or suggestions.

Figured this out. I opened dev tools and tried to load the site and saw that some instafeed.css was hanging, and the site loaded once it finally timed out and failed. Removed a line from theme.liquid and my site started loading quickly again.
