Around 5pm UTC on 29th October there was a large spike in traffic across all wikis for startup error limited to the desktop. Due to the nature of the errors this is likely interfering with use of desktop. At time of writing 25,608 errors have been recorded since the inciting incident.
Does anyone know what could be causing this? Given the lack of deploys this week, no backports in the evening and sharp uptick, could this be a banner campaign?
