Work through the checks below in order. You'll probably find the cause before you need to contact support.
1. Check if Squarespace is down
Before changing anything, make sure it's not a system-wide issue. Squarespace's infrastructure is reliable, but like any hosted platform it occasionally has regional outages or delayed deploys that affect a subset of sites.
How to check:
Visit status.squarespace.com, Squarespace's official service status page.
Check social media (like X/Twitter) for #SquarespaceDown updates.
Try loading your site on a different device or network.
If the platform is experiencing downtime, all you can do is wait until Squarespace resolves it. They usually fix outages quickly, and there's nothing you can do on your end to speed that up. Resist the urge to start changing settings, since that can create a second problem layered on top of the first. It's worth bookmarking the status page now, before anything goes wrong, since it's the fastest way to rule out an entire category of problems in under a minute during an actual outage.
2. Domain connection issues
If your domain isn't pointing correctly, your site might look like it's down even though it's live on Squarespace. This is one of the most common causes of a "the site's not working" panic, especially right after a domain transfer or a registrar renewal.
Fix it:
Go to Settings, then Domains inside Squarespace.
Make sure your custom domain shows "Connected."
If not, follow the on-screen prompts to reconnect or verify your DNS records.
For third-party domains (like Google Domains or GoDaddy), confirm that your A and CNAME records match Squarespace's current requirements. DNS changes can take anywhere from a few minutes to 48 hours to fully propagate, so if you've just made a change, give it time before assuming something else is wrong. A quick way to check propagation without guessing is a free DNS checker tool, which shows whether your new records have actually reached the servers your visitors' devices are querying, or whether older, cached records are still being served in some regions.
It's also worth checking whether your domain registration itself has expired rather than just its connection settings. An expired domain looks identical to a broken connection from the visitor's side, a blank page or an error, but the fix is entirely different: renewing the domain at the registrar, not touching anything inside Squarespace.
3. Browser or cache problems
Sometimes your Squarespace website not working issue isn't the website at all, it's your browser holding onto an old, cached version of the page.
Try this:
Clear your browser cache and cookies.
Try loading the site in a private or incognito window.
Test in another browser (like Chrome, Safari, or Firefox).
If your site loads elsewhere, the problem is likely a local cache issue and not your Squarespace setup. It's worth checking from a phone on mobile data too, since that rules out both your browser and your home wifi network at once. If a colleague or a friend on a completely different network can load the page fine while you can't, that's a strong signal the problem lives on your end, not the site's. Browser extensions, especially ad blockers and privacy extensions, are worth disabling temporarily too, since some of them block scripts that Squarespace relies on to render certain sections properly.
4. Custom code conflicts
If you've recently added custom HTML, CSS, or JavaScript, that's a common culprit when your Squarespace website stops working.
How to fix:
Go to Settings, then Advanced, then Code Injection.
Temporarily remove any recent code additions.
Refresh your site and test again.
Even a single missing bracket or extra tag can cause sections to break or disappear. Always back up custom code before editing, paste it into a plain text file first, so you can restore it once you've isolated the problem. If you have several code snippets running at once, footer scripts, header scripts, and page-specific code blocks, remove them one at a time rather than all together, and reload the site after each removal. That way you know exactly which snippet caused the problem instead of guessing among several possible culprits at once.
5. Expired subscription or billing issues
If your Squarespace site suddenly went offline, check your billing settings. Expired payment methods or lapsed subscriptions can cause your site to go into "grace period" or "deactivated" mode.
Check:
Settings, then Billing & Account, to confirm payment details.
Look for any alerts in your dashboard about renewal or failed payments.
Squarespace typically gives a warning before fully deactivating a site, but it's easy to overlook, especially if the notification email lands in a spam folder or goes to an inbox nobody checks anymore. If your business has changed banks or updated a card recently, that's worth checking first, since an expired card is the single most common reason a subscription lapses without anyone noticing until the site itself goes dark.
6. Plugin or third-party integration issues
If your site uses external tools, like scheduling apps, email forms, or analytics, one of those integrations could be causing the error.
Try temporarily removing or disabling integrations one by one to isolate the problem. If the site starts working again, you've found your culprit. This is especially common with embedded booking widgets and chat tools, which sometimes push updates on their end that conflict with how they're embedded on yours. A widget that worked perfectly for a year can suddenly break overnight simply because the third-party provider changed something on their side, with no changes made to your Squarespace site at all.
It's worth keeping a short list of every third-party tool embedded on your site, its purpose, and where it's embedded, so that when something breaks you can work through that list methodically instead of hunting through pages trying to remember what you added and when.
7. Slow loading or design glitches
If your site loads slowly, sections overlap, or fonts appear broken, you may be dealing with:
Large uncompressed images
Too many custom animations
Outdated browser versions
Squarespace sites are generally fast, but heavy media files or unnecessary scripts can drag performance down. Use the Squarespace Page Speed report or Google PageSpeed Insights to identify bottlenecks. Pay special attention to hero images and video backgrounds, they're usually the single biggest contributor to a sluggish first load. A full-screen background video on the homepage, in particular, is worth testing on mobile specifically, since it often behaves very differently on a phone connection than it does on the office wifi you built the site with.
8. Preventing the next outage before it happens
Most of the issues above are avoidable with a few habits: keep a record of any custom code you add, avoid stacking multiple third-party scripts without testing between each one, and check your billing settings quarterly rather than waiting for a warning email. A simple pre-publish checklist, preview on mobile, click every nav link, submit every form, catches the majority of these problems before a visitor ever sees them.
It also helps to keep a short written log every time you add or remove a code snippet or integration, just a date and one line describing the change. When something breaks weeks later, that log turns a guessing game into a two-minute lookup, since you can see exactly what changed and when, rather than reconstructing months of edits from memory under time pressure.
9. Bonus tip: Contact Squarespace support
If you've tried everything and your Squarespace website still isn't working, contact Squarespace Support. They offer 24/7 chat assistance and can look into account-specific issues you can't access directly. When you reach out, it helps to have already ruled out the categories above and to describe specifically what you tried, since that lets their team skip straight to the account-level checks only they can perform, rather than repeating the same first few troubleshooting steps you've already covered.
Conclusion
Start with Squarespace's status page, then check your domain, browser, code and billing, in that order. If you're still stuck, contact Squarespace support and tell them what you've already tried. If you'd rather not deal with this again, our Maintain plan keeps an eye on the site for you.
FAQ
Why is my Squarespace website suddenly not loading?
When a Squarespace website suddenly stops loading, the cause is usually a platform outage, your domain, your browser, custom code or billing. Check Squarespace's status page first. If there's no outage, check your domain connection and billing next. Then try the site on your phone using mobile data, which rules out your browser and your home wifi at once. If it loads there, clear your cache or turn off ad blockers, which can block scripts Squarespace needs.
How do I know if Squarespace is down or if it's my site specifically?
Check Squarespace's status page. If an outage is listed, all you can do is wait, and changing settings can create a second problem on top of the first. If nothing is listed, the problem is probably on your side, usually your domain, billing or code. An incident can take time to appear, so check again in a few minutes. Bookmark the status page now so you can rule out an outage in under a minute.
Can custom code break my Squarespace website?
Yes, custom code can break your Squarespace website. Even one missing bracket or extra tag in custom HTML, CSS or JavaScript can make sections break or disappear. If the problem started after an edit, remove your latest code first and see whether the page comes back. With several snippets, remove them one at a time and reload after each, so you know exactly which one caused it. Save a copy of your code in a plain text file before you edit.
What happens to my Squarespace site if my subscription lapses?
If your subscription lapses, your Squarespace site can go into a grace period or be deactivated, which takes it offline. Squarespace usually warns you first, but that email is easy to miss if it lands in spam. Check billing in your account and update your card, since an expired card is the most common reason a subscription lapses. Check your domain renewal too, because it can be billed separately.
How can I prevent Squarespace issues from happening again?
A few simple habits prevent most Squarespace issues. Keep your card and domain renewal up to date, and check billing every quarter rather than waiting for a warning email. Keep a short log of every code snippet you add, with a date and one line about the change. Before you publish, preview on mobile, click every menu link and submit every form. Or hand those checks to someone else, which is what our Maintain plan does.
