On the 26 February 2024 the ISC had an internet outage, the issue has been resolved
Due to a wide internet issue in the area, our websites (e.g., www.isc.ac.uk and BSM conference website bsm2024.isc.ac.uk ) as well as our email system are currently down. The issue is being investigated by British Telecom and we hope that soon we will be able to restore our services
