Experiencing

Citibank

outages? You’re not alone.

Here’s how to confirm if Citibank is down:

• Check the Citibank Website: Visit citibank.com.au for banners or login-page alerts. Scheduled maintenance or outages are often posted here.
  
  
• Use the Citi Mobile® App: Look for push notifications or in-app error messages (e.g. “We’ve encountered an issue”) that may indicate a wider problem.
  
  
• Payment Service Availability Page: Review Citi’s Operational Incidents & Quarterly Reports for historical service interruptions.
  
  
• Check Outage Trackers: See Downdetector for user-reported issues.
  
  
• Social Media & Forums: Follow @AskCiti on Twitter or check Reddit threads (e.g. r/AusFinance) for customer reports.
  

If you believe Citibank is experiencing an outage:

• Call Citi Customer Service: 13 24 84 (Australia, 24/7) or +61 2 8225 0615 (overseas).

• Message on Social Media: Reach out to @AskCiti on Twitter or Citibank Australia’s Facebook page.

Citibank outages are rare, but notable recent examples include:

• April 29, 2025 – Global Online Banking Outage (~1 hour): Customers worldwide, including Australia, were locked out of accounts and saw declined transactions. Citi fixed the issue within an hour.
  
  
• February 18, 2025 – Login Disruption (<1 hour): A small glitch caused login issues for some users, quickly resolved by Citi’s IT team.
  
  
• June 2025 – Card Payment Network Failure (2 hrs 55 mins): An external payment infrastructure issue prevented card transactions for nearly 3 hours.
  
  
• System Migrations (2024–25): As NAB integrated Citi’s consumer banking, some services experienced scheduled downtime during planned migrations.
  

Most outages have been caused by technical faults or third-party network failures (e.g. Visa/Mastercard or Osko/NPP).

• Minor Issues (login/app errors): Usually fixed in under 1 hour.
  
  
• Major Outages (all online access or card declines): Typically resolved in 1–4 hours, often within the same day.
  
  
• Extraordinary Events: Prolonged outages are extremely rare. Citi has 24/7 global IT teams to ensure rapid recovery.
