Update 1054 11 April 2024

SYSTEM DOWNTIME 10 April 2024: We apologise for the recent system downtime, which was caused by a Denial of Service (DOS). HOPS received several million connection requests from a single location within a 24-hour period which overwhelmed the web server. Overnight the HOPS program team have configured a DOS protection system which will limit the number of connections that can be made from one IP address. Any IP address which triggers a limit will be blocked for a short period of time. We believe the configured limits to be very reasonable and we anticipate that there will be no disruption to legitimate uses of HOPS. For security reasons we are not publicising these limits but will continue to monitor and adjust them to reduce any user impact. Please open a helpdesk ticket if you believe you have been blocked and we will investigate this for you. We appreciate your patience while we investigated this problem.
