Critical IT system not working. Business blocked.Resolved today.

PM assigned in 10 minutes. IT engineer starts diagnosing within the hour. Microsoft 365 SSO failures are almost always caused by: an expired SAML certificate in Azure AD needing renewal and re-upload to the identity provider, a conditional access policy blocking sign-in for a user group after a recent policy change, an MFA enforcement change that locked out users who had not enrolled, or a federation configuration break after a domain change. The engineer accesses your Azure AD admin portal with scoped permissions, traces the exact sign-in failure error code in the Azure AD sign-in logs, and implements the fix. For certificate expirations the repair takes under 30 minutes. Most SSO outages are resolved within the hour, restoring access for all affected employees.

PM assigned in 10 minutes. Network engineer starts diagnosis within the hour. VPN outages are most commonly caused by: a certificate or license expiration on the VPN gateway appliance, a routing table change breaking split tunnelling configuration, a cloud security group rule change blocking inbound VPN traffic on required ports (UDP 500, UDP 4500 for IKEv2), or a DNS resolution failure preventing clients from resolving the VPN gateway hostname. The engineer works remotely using out-of-band access you provide (management console, bastion host, or direct console access) and restores service. If the VPN is completely inaccessible, PM helps you establish a temporary secure alternative while the fix is implemented.

Yes, as long as you have out-of-band remote access an IPMI or iDRAC console, a secondary management network, or a bastion host reachable independently of the broken system. The engineer works through whatever remote access you provide: SSH, RDP, IPMI console, AWS Systems Manager Session Manager, or Azure Bastion. For environments where the primary remote access is down (VPN down, RDP gateway broken), PM helps you assess what alternative access path exists before the session starts so the engineer is not blocked. On-premise server work Windows Server, Linux (Ubuntu, RHEL, CentOS), VMware vSphere, Hyper-V is standard for QuickHire IT specialists matched to your specific environment.

PM confirms whether the outage is internal or external in the first 10 minutes. If confirmed as a cloud provider incident (AWS, Azure, GCP regional outage on the status page), the engineer implements failover and mitigation: routing traffic to a backup region, enabling static cached content via CDN, switching to backup DNS, or disabling features dependent on the unavailable service so the rest of your platform continues. If it is an ISP issue, the engineer configures failover to a secondary ISP or mobile backup if your infrastructure supports it, and documents the business continuity procedure for future incidents. You receive a written incident report and failover runbook at session close.

The vast majority of enterprise IT issues are resolvable remotely. Consistently remote-resolvable: Azure AD, Microsoft 365, and Google Workspace user account issues, cloud infrastructure configuration (AWS, Azure, GCP), VPN gateway configuration with out-of-band management console access, DNS configuration, email delivery issues (SPF, DKIM, DMARC, delivery blacklist removal), software deployment via MDM (Intune, Jamf), network device configuration with console access, and any server-side application issue where the server is reachable via an alternative access method. Issues requiring on-site presence: physical hardware failure, cable runs and physical network installation, and workstations that have lost all remote access capability and cannot be reached via MDM or network boot.
