Post-Incident Summary: United Kingdom – External Connectivity Issue – December 4, 2025
Incident Overview
On December 4, 2025, some customers in the United Kingdom – primarily those using Sky Broadband – experienced difficulty accessing the Actionstep login page. This login page (also known as the Launchpad) is hosted in the ap-southeast-2 region; however, no customer data for UK systems is stored or processed in this region. Once a user selects their system, they are directed to the appropriate UK/region-specific server where their data resides.
Our investigation confirmed that this incident was caused entirely by a Sky ISP routing/connectivity issue preventing requests from reaching a wide variety of services hosted in ap-southeast-2. Actionstep also contacted AWS, who confirmed we were one of hundreds of services affected by the Sky outage. There was no issue with the Actionstep platform, AWS infrastructure, or our regional hosting.
The issue began at approximately 2:30 pm GMT on December 4, 2025, and normal access was fully restored by December 9, 2025
Impact
Customers in the UK using Sky Broadband were intermittently or completely unable to reach the Actionstep login page due to Sky’s network routing issue.
Customers using other ISPs, or those switching to an alternative connection such as mobile data, were able to access Actionstep normally.
At all times, the Actionstep platform itself remained operational.
Resolution
Once Sky resolved their connectivity issue, normal access to the Actionstep login page was restored.
Throughout the incident, Actionstep systems continued to perform normally, and users connecting from unaffected networks experienced no disruption.
Next Steps
No Actionstep changes are required, as the root cause was external to our systems and infrastructure.
If customers encounter similar symptoms in the future, we recommend testing an alternative connection (such as a mobile hotspot) and contacting their ISP to confirm whether a localised network issue is occurring.
Acknowledgement
We recognise that this caused inconvenience for affected customers and appreciate everyone’s patience while Sky resolved their network routing issue. Ensuring reliable access to Actionstep remains our priority.
