Is Oracle Cloud Infrastructure (OCI) Down Right Now?
Compute instances unreachable, Autonomous Database connections failing, API calls timing out — OCI outages affect enterprise workloads running ERP, financial systems, and Oracle-native applications. This guide covers OCI status by region and service.

Check Oracle Cloud Status Now
OCI's official status page shows health by region and service. Select your specific region (US East, EU Frankfurt, etc.) to see targeted incidents:
OCI Service Components
OCI is organized by region → availability domain → fault domain. A service degradation in one availability domain doesn't necessarily affect others in the same region. Always identify the scope before escalating.
Virtual and bare metal instance lifecycle
Self-managing Oracle Database (ATP/ADW)
Managed MySQL with in-memory analytics
VCN, subnets, security lists, gateways
S3-compatible object storage
Users, groups, policies, federation
Serverless Functions as a Service (FaaS)
Managed Kubernetes clusters
External monitoring for OCI — catch regional outages before your enterprise does
OCI incidents are often region-scoped and discovered late when your enterprise apps start throwing errors. Better Stack monitors your OCI-hosted endpoints from external vantage points across regions — so your ops team knows about degradation before your CFO asks why the ERP is down.

OCI issues are frequently network or IAM policy-related rather than platform outages. Work through this checklist systematically.
Check ocistatus.oraclecloud.com for your region
Select your region from the dropdown. OCI incidents are typically region-scoped — a US East issue doesn't affect EU Frankfurt. Subscribe to status updates for each region where you run workloads.
→ Oracle Cloud Status PageCheck Security Lists and NSGs
Go to OCI Console → Networking → Virtual Cloud Networks → [your VCN] → Security Lists. Verify SSH (port 22) or RDP (3389) inbound rules exist for your subnet. NSGs override Security Lists — check both.
Verify instance state and console access
OCI Console → Compute → Instances → [instance] → check state is "Running". Use OCI Console → Serial Console to access the instance's serial terminal even if SSH is broken — useful for diagnosing boot failures or full disk issues.
Test OCI API connectivity
Verify the OCI API is reachable: `curl https://iaas.us-ashburn-1.oraclecloud.com/ -o /dev/null -w "%{http_code}"`. A 404 is expected (API needs auth) — it confirms DNS and network reach. Connection refused or timeout means the API endpoint is down.
Check OCI Service Limits and quotas
OCI enforces service limits by region. Go to OCI Console → Governance & Administration → Limits, Quotas and Usage. If you hit a limit (e.g., max shapes per AD), provisioning fails silently with cryptic errors.

Frequently Asked Questions
Is Oracle Cloud Infrastructure (OCI) down right now?
Check the official OCI status page at ocistatus.oraclecloud.com. It shows health by region (US East, US West, EU Frankfurt, UK South, AP Tokyo, etc.) and by service (Compute, Database, Networking, Identity, Object Storage, Functions). OCI incidents are typically contained to a single availability domain or region — check whether your specific region and service are affected before escalating.
Why are my OCI compute instances unreachable?
OCI compute instance connectivity failures: (1) OCI regional incident — check ocistatus.oraclecloud.com for your region. (2) Security List or Network Security Group (NSG) change — check if SSH/RDP rules were modified; OCI defaults to deny-all inbound. (3) Instance lifecycle state — verify in OCI Console → Compute → Instances the instance shows "Running" (not "Stopped" or "Terminating"). (4) Public IP not attached — OCI Flexible shapes don't auto-assign public IPs; verify instance has a public IP or use a Bastion service. (5) VCN route table issue — verify your VCN has an internet gateway route (0.0.0.0/0 → Internet Gateway) in the route table attached to the public subnet.
Why is my Oracle Autonomous Database connection failing?
Oracle Autonomous Database (ADB) connection failures: (1) OCI Database service outage — check ocistatus.oraclecloud.com. (2) Wallet not configured — ADB requires a client credentials wallet (download from OCI Console → ATP/ADW → DB Connection). (3) ACL restriction — ADB has an IP-based Access Control List; if your IP isn't whitelisted, connections are rejected. Check in OCI Console → ADB → Access Control List. (4) mTLS requirement — by default, ADB requires mTLS; if you're using a connection string without a wallet, enable TLS-only in ADB settings. (5) ADB CPU throttling — check Activity Monitoring in OCI for CPU utilization and statement queuing.
What is OCI's architecture for high availability?
Oracle Cloud uses a Fault Domain architecture: each Region contains multiple Availability Domains (AD), and each AD contains multiple Fault Domains (FD). Distributing workloads across FDs (3 per AD) and ADs protects against hardware failures. For cross-region HA, use OCI's Data Guard for databases and custom failover logic for compute. OCI's Always Free tier uses a single AD; paid workloads should use multi-AD placement for SLA-backed availability of 99.9% (compute) to 99.95% (Autonomous Database).
How do I get notified when Oracle Cloud is down?
Use multiple monitoring approaches: (1) Subscribe to ocistatus.oraclecloud.com RSS feed or email alerts for your regions. (2) Use OCI Service Connector Hub to route Audit logs to a monitoring system — create an alarm in OCI Monitoring for service error rates. (3) Set up Better Stack to monitor your OCI-hosted endpoints from external locations — critical for detecting regional outages before your internal OCI monitors are affected. (4) Use OCI Health Checks (built-in) to probe your load balancers and compute instances every 10 seconds. (5) Configure OCI Alarms for CPU, memory, and network metrics on critical instances.
