Day notes - Tue 15th Feb 2011
Kalv and I paired on some message encoding oddness we’re seeing with certain messages coming to us from the SMSCs.
Tom and I paired to investigate some spikes in load we were seeing on our application server after re-enabling a number of #blue users yesterday. We’re fairly confident we found at least two of the main offenders: removing conversations and cancelling accounts were both using grossly inefficient queries. We’ve tidied these up and re-deployed.
