There were few similar spikes of timeouts in last 7 days we noticed. Not as large, only in order of tens of thousands timed-out requests. Unlike the one mentioned originally, they are only from specific location: On Nov 5th, 9:40am UTC; Nov 6th, 5:53am UTC and Nov 8th, 6:34am UTC, timeouts towards APNS spiked in India, on Nov 5th, 11:11am UTC, in US and on Nov 4th, 8:42am UTC ( which is probably out of 7days scope), in EU. Most affected seem to be APNS requests for bundle with App ID com.microsoft.skype.teams. Since those are timeouts, we did not have and log responses with apns ids. Please, let us know if you are aware of some outage/update/network issue or anything else that could have caused these timeouts on your side. We are also investigating on our side.
