Caroline Lucas, MP for Brighton Pavilion and Pip Griffin, SEACAmb Unison Rep, react to the Critical Incident
Computer systems at South East Coast Ambulance Service are now back online, after a significant IT issue affected operations.
The service tweeted to say systems are now 'functioning fully'.
SECAmb said in a post on Twitter: "We’d like to say a massive thank you to our staff & volunteers for their outstanding work today, as well as to our fellow amb trusts, our hospital & system partners for their support.
"We’d also like to thank our patients & the public for their patience & understanding."
An IT failure overnight disrupted ambulance dispatch systems and a 'critical incident' was declared on Wednesday (17 November).
During the IT issues, other ambulance trusts and system partners stepped in to help take calls.
