Chase Bank services may be disrupted during a major Microsoft outage, but the bank's own systems usually stay running

When Microsoft experiences a widespread outage — like the one in July 2024 caused by a faulty update to CrowdStrike software — Chase Bank's core banking systems typically remain operational. Chase runs its own data centers and does not depend entirely on Microsoft's cloud infrastructure for basic banking functions. However, some Chase services and tools may slow down or become temporarily unavailable if they rely on Microsoft products like Azure, Office 365, or Windows servers.

The impact depends on which service you are trying to use. You may still be able to log into your account, check your balance, and transfer money between your own accounts during a Microsoft outage. But some features — like bill pay, mobile app functions, or customer service chat — could be affected if those specific systems depend on Microsoft infrastructure.

Key Takeaways

  • Chase's main banking systems usually stay online during Microsoft outages because the bank operates its own infrastructure separate from Microsoft's cloud services.
  • Some Chase services may slow down or go offline if they specifically depend on Microsoft products like Azure or Office 365.
  • During an outage, you can check your account status on Chase's website or call 1-800-935-9935 to confirm which services are affected.
  • If you cannot access Chase online or mobile banking, visit a branch in person or use an ATM to withdraw cash while you wait for service to return.
  • Chase publishes outage updates on its social media accounts and website, so checking those sources gives you real-time information about what is down.

How Chase systems connect to Microsoft infrastructure

Chase uses Microsoft products in specific parts of its operation, not across the entire bank. The bank relies on Microsoft Azure for some cloud-based services, Microsoft Office 365 for employee email and productivity tools, and Windows servers for certain internal systems. When Microsoft experiences a major outage, any Chase service built on top of those platforms can go down alongside them.

However, Chase's customer-facing banking systems — the servers that hold your account balance, process transfers, and run the core deposit and lending operations — are not entirely dependent on Microsoft. The bank has invested heavily in its own infrastructure and redundancy, which is why you can usually still access basic account functions even when Microsoft is down. The distinction matters: a Microsoft outage is not the same as a Chase outage.

Which Chase services are most likely to be affected

Chase Mobile App and Chase.com may experience slowdowns or temporary unavailability during a Microsoft outage, depending on how those platforms are built. Bill Pay, Zelle transfers, and some automated customer service features could also be disrupted if they run on Microsoft infrastructure. The bank's website may load slowly or show error messages if the servers handling that traffic depend on Azure or other Microsoft services.

Services least likely to be affected include ATM withdrawals, in-branch transactions, and basic account access through older systems. If you need cash or want to speak to a banker in person, a branch visit is usually your most reliable option during a widespread outage.

What to do if you cannot access your Chase account

First, confirm that the outage is actually affecting Chase and not just your own internet connection. Restart your router, clear your browser cache, or try a different device. If the problem persists, check Chase's official social media accounts (Twitter, Facebook) or visit Chase.com to see if the bank has posted an outage notice.

If Chase services are indeed down, you have several options. Call Chase customer service at 1-800-935-9935 to speak with a representative who can help you with urgent account questions. Visit a Chase branch in person if you need to withdraw cash, deposit a check, or handle a time-sensitive transaction. Use an ATM to withdraw cash if you need immediate access to funds. For non-urgent matters, wait for the outage to resolve and try again later.

How long Chase outages typically last

The duration depends on the severity and scope of the Microsoft outage. The 2024 CrowdStrike incident affected systems worldwide for several hours to a full day as companies rolled back the faulty update. Smaller, localized Microsoft issues may resolve in minutes or an hour. Chase cannot fix a Microsoft outage on its own — the bank must wait for Microsoft to resolve the problem on their end, then verify that Chase services are working again.

During that waiting period, Chase's communications team usually posts updates on the bank's website and social media. These updates tell you which services are affected, when the bank expects them to return, and what alternatives are available. Checking those sources regularly gives you the most current information rather than calling customer service, which may be overwhelmed with calls during a major outage.

Protecting yourself during banking outages

Keep some cash on hand so you are not stranded if you cannot access ATMs or branches. Know your account number and routing number by heart or write them down somewhere safe — you may need them if you have to call customer service and cannot log in to verify your identity. Set up alerts on your Chase account for large transactions, so you know if something unusual happens even if you cannot access your account directly.

If you have bills due during an outage, contact your creditors to let them know you are experiencing a banking issue. Most companies will work with you if you can show proof that a service outage prevented payment. For recurring bills, consider setting them up through your employer's payroll system or through the biller's own website rather than relying solely on Chase Bill Pay.

Frequently Asked Questions

Will a Microsoft outage cause me to lose money in my Chase account?

No. Your money is stored in Chase's own systems, not in Microsoft's cloud. Even if you cannot access your account during an outage, your balance and transactions are safe. Once services return, you will see all your account activity as normal.

Can I still use my Chase debit card if Microsoft is down?

Yes. Your debit card works through the payment network and Chase's card processing systems, which are separate from Microsoft infrastructure. You can swipe or insert your card at stores and ATMs during a Microsoft outage without any problem.

What if I need to pay a bill and Chase online banking is down?

Call the company you owe money to and ask if you can pay directly through their website or by phone. Many utilities, credit card companies, and loan servicers let you make one-time payments without going through your bank. If the outage lasts more than a day, contact your creditors to explain the delay and ask about grace periods.

How do I know if Chase is down or if it is my internet connection?

Try accessing Chase on a different device using a different internet connection (like your phone's mobile data instead of WiFi). Check Chase's social media accounts and website for outage announcements. If other websites load fine but Chase does not, the problem is likely on Chase's end or with Microsoft services Chase depends on.

Should I switch banks because of outages?

Outages happen to every bank and every cloud provider. Chase's outages are typically brief and do not affect your money. If you need banking services during an outage, having a backup account at a different bank can help, but switching entirely is not necessary unless you have other reasons to change banks.
