This morning we had a number of small outages affecting domestic transit (and also some international services which peer domestically e.g. Microsoft Office). This was caused by a line card in one of our upstream providers routers causing traffic to be re-routed over backup networks. These 30 second outages happened at 08:29, 09:05 and 08:54. We are working with our upstream provider on the issue, please contact us if you have any further network issues.
