Thank you Argun. We will try to investigate more on our side and even improve our request logic and logging to be able to get at least some sample of APNS-id even for requests that timeout.

Only smaller spikes in last 7 days. Please, check these times (and locations): 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. Most affected are APNS requests for bundle with App ID com.microsoft.skype.teams. No APNS IDs for timeouts. Please, let us know if you are see some outage/update/network issue or anything that could have caused these timeouts on your side. We are also investigating on our side.
