We switched our SSL certificate for all inbound traffic from Tideways daemons only and some clients experienced SSL handshake errors. We have reverted to the old configuration for now and will investigate how to fix the SSL errors before switching again.
For affected customers between 20:10 and 20:40 some daemons may have stopped reporting. This affected about 5% of all reporting servers before we reverted back, but was highly localized to 16 customers. Immediately after reverting at 20:38 traffic from these servers bounced back to the previous levels.
