Platform has been fairly unstable for the past few days. When I call the IG telephone number I get a dead tone. Tried with my mobile and landline. Like others, I have had issues with positions disappearing. However, it's really good that the outage status has at least been updated relatively quickly here https://status.ig.com/ giving me some confidence.
Also it's good that the underlying infrastructure has been robust enough not to lose new positions I have opened.
