For the better part of a day, thousands of people opened Cash App and Square and hit a wall: payments wouldn’t send, Cash Cards were declined at checkout, and — most alarming of all — balances and bitcoin appeared frozen or invisible. If you lived through an outage like this, or you’re bracing for the next one, the two questions on your mind are simple: what actually happened, and is my money gone?
The short answer to the second question is reassuring: an outage is a connectivity problem, not a money problem. Your funds don’t disappear when the app can’t load — they’re sitting in bank accounts and custody systems that keep their own records, independent of whether the screen shows the right number. Let’s walk through the details.
What Happened During the Big Cash App and Square Outage
The most significant outage on record hit on September 7–8, 2023, when Block (the parent company of both Cash App and Square) suffered an internal failure that knocked out payments across both platforms for more than half a day. Merchants couldn’t run Square card readers, and Cash App users couldn’t send money, cash out, or reliably see their balances.
According to Block’s own post-incident analysis published on the Square developer blog, the culprit was an internal DNS (Domain Name System) failure — not a hack. An unrelated change to Block’s host-based firewalls collided with a DNS service upgrade. A small policy change expanded into a far larger ruleset than intended, which destabilized internal servers and caused the company’s own systems to fail at looking each other up. In plain English: the different parts of Block’s network temporarily lost the ability to find and talk to one another.
Two things matter here. First, a forensic review ruled out a cyberattack and found no evidence of a data breach or data loss. Second, because the problem was internal plumbing rather than the underlying ledgers, customer balances were never actually spent, drained, or deleted — they just couldn’t be reached in real time.
Outage Timeline at a Glance
| Time (ET) | What happened |
|---|---|
| ~1:54 PM, Sep 7 | Internal DNS servers begin failing; payments and app functions break |
| Afternoon–evening | Square sellers can’t process cards; Cash App sends and cash-outs fail |
| ~2:05 AM, Sep 8 | Systems begin recovering; add cash, Cash Card, and buying bitcoin come back first |
| ~5:19 AM, Sep 8 | Payment services broadly restored — roughly 14+ hours after it started |
Notice the recovery order: Cash App restored the ability to add cash, make Cash Card purchases, and buy bitcoin before it fully restored sending money and cashing out. That’s typical — companies bring services back in stages as stability returns, which is why your app might partially work mid-recovery.
Is Your Cash App Balance Safe When the App Is Down?
Your Cash App balance is not stored “inside the app.” It’s held at Block’s partner banks — Sutton Bank, The Bancorp Bank, N.A., and Wells Fargo, N.A. (all Members FDIC) — which keeps your money separate from Block’s business operations. When the app can’t load, those bank records still exist. The number you can’t see is still on the books.
Here’s the nuance that trips people up: FDIC “pass-through” insurance is not automatic. Your Cash App and Savings balances become eligible for pass-through coverage (up to $250,000 per customer, aggregated with any other deposits you hold at the same bank in the same capacity) when you have a Cash App Card or sponsor a sponsored account. If you just downloaded Cash App and shuttle money back and forth without ever ordering a Cash Card, the balance sitting there may not be federally insured.
One more distinction: FDIC pass-through protects you if the partner bank fails — it does not cover losses from the app having a bad day. But an outage isn’t a bank failure and isn’t an insurable “loss” at all. It’s downtime. Your recourse during an outage is patience and support, not an insurance claim.
What About Your Bitcoin?
Bitcoin is a different animal. Bitcoin (and Investing/stock holdings) are not covered by FDIC insurance — and bitcoin isn’t SIPC-insured either. Your bitcoin is custodied by a Block affiliate. During the 2023 outage, the coins themselves weren’t going anywhere; the blockchain kept running, and Block’s custody records were intact. The app simply couldn’t display or trade them for a while.
The real takeaway for crypto isn’t outage-specific: because bitcoin has no deposit insurance, its safety rests on Block’s custody arrangements and, in a worst case, on contract and bankruptcy law — not on a government guarantee. That’s a reason to think carefully about how much crypto you keep on any single app, outage or not.
A Worked Example: Maria’s Frozen Balance
Say Maria has $640 in her Cash App balance, a $180 pending deposit, and 0.01 BTC. Mid-outage, her app shows an error and her Cash Card is declined at the grocery store. It feels like the money vanished. Here’s the reality:
- Her $640 is recorded at a partner bank and never left.
- Her $180 deposit is queued; it posts once systems reconnect (direct deposits are sometimes delayed but not lost).
- Her 0.01 BTC is still held in custody and reappears when the app can read it again.
What Maria should not do is send the same payment five times because it looks stuck — duplicates can post later and create real headaches. The right move is to wait for recovery, then confirm balances.
What To Do During a Cash App or Square Outage
- Confirm it’s an outage, not just you. Check Block’s status pages and Downdetector before assuming your account is compromised.
- Stop retrying failed payments. Repeated sends can double-charge once the queue clears.
- Keep a backup payment method. If you run a business on Square, have a fallback (a second processor, or a manual card-entry plan) for outage days.
- Screenshot errors and note times. Useful if a transaction posts oddly and you need support.
- Wait for staged recovery. Some features return before others — a partial app doesn’t mean your money is at risk.
- Reconcile afterward. Once restored, check your balance, pending deposits, and bitcoin, and confirm no duplicate transfers went out.
Frequently Asked Questions
Did anyone lose money in the Cash App/Square outage?
No. Block’s forensic review found no data breach and no data loss, and balances were never spent or deleted — they were temporarily unreachable. The main real-world cost fell on merchants who couldn’t process sales during the downtime, not on funds disappearing from accounts.
Is my Cash App balance FDIC insured?
It can be, through pass-through insurance at partner banks (Sutton Bank, The Bancorp Bank, and Wells Fargo), up to $250,000 — but generally only if you have a Cash App Card or a sponsored account. It isn’t automatic just because you have the app, and it doesn’t cover outages, since downtime isn’t an insurable loss.
Is my bitcoin protected if Cash App goes down or fails?
Your bitcoin isn’t covered by FDIC or SIPC insurance. It’s held by a Block affiliate as custodian. An outage doesn’t put your coins at risk, but because there’s no deposit insurance, don’t treat any app as a vault for large crypto holdings.
How long do Cash App outages usually last?
Most are brief — minutes to a couple of hours. The 2023 DNS outage was unusually severe at 14+ hours. Recovery is typically staged, so expect some features to return before others.
The Bottom Line
An outage is scary precisely because it hides your money from view — but hidden isn’t gone. The 2023 Cash App/Square outage was an internal DNS failure, not a hack, and no funds were lost. Your dollars live at insured partner banks, and your bitcoin sits with a custodian, whether or not the app can show them to you in the moment. The smartest protection is boring but effective: keep a backup payment method, avoid panic-retrying stuck payments, order a Cash App Card if you want FDIC pass-through eligibility, and don’t stockpile more crypto on any single app than you’d be comfortable waiting out a bad day with.
