Slower loading speed of Impact Stack sites
Resolved | Feb 27, 2024 | 12:00 GMT+01:00
Impact Stack sites were loading slower than usual on Tuesday, 27th February. This issue has now been resolved.
After investigating, we found that the reduced loading speed was caused by an external service 'polyfill.io' being down for around 3 hours. We use polyfill to let people with older browsers use Impact Stack.
As a result of this incident we have added further monitoring of the polyfill service and are reviewing our future use of polyfill.

Temporary interruption in outbound email delivery
Resolved | Nov 16, 2023 | 14:29 GMT+01:00
Between Saturday November 11th ~00:00 CET and Monday November 13th ~10:00 AM CET no emails were sent out for Impact Stack action pages (confirmation-, thank-you- and email-to-target emails were affected). All emails that needed resending have been resent.
The incident was caused by an upgrade of our mail server on November 7th, which introduced a bug that caused part of the mail server to brake on November 11th because it was overloaded. The bug has been fixed and further steps have been taken to stabilise the mailing system to ensure the same problem doesn't happen again. We have also improved our monitoring systems to make sure that similar problems are detected and resolved within a shorter period of time.

On Friday morning, 30th July between 9:11 - 9:42 CEST, our webservers experienced an unexpected downtime, due to a deliberate DDoS (Distributed Denial of Service) attack on one of our client installations with the goal to overload our servers. This affected all sites and resulted in slower loading speed or unavailability during that time.
The issue has now been resolved and all services are running as they should.
We understand that unscheduled downtime is, at the very least, inconvenient, and we're sorry this has happened. Our team is working hard to prevent incidents like this from happening again in the future.
