This incident has been resolved.
We believe the issue was caused by a network route to Equinix, where 90% of trading brokers have their servers.
The congestion appears to be resolved and trading speeds have improved.
This issue was not an issue with our platform itself.
We are receiving reports of several broker servers having delayed execution speeds.
Our development team are investigating the issue, at this point we do not believe the delay is with our platform itself.
