Does any one else have SSL handshake spikes with the website monitor? and a way to troubleshoot them on nginx?
I have noticed this more from some testing locations than others and at times correlates to DNS and response time spikes, which could indicate issues with the testing location or the way it's measured.
Any ideas on what could be causing these?
Hello,
The SSL handshake time begins after the TCP socket's connection time. If you see a corresponding increase in the connection time alongside the SSL handshake time, then it's possibly a network latency issue. It's not uncommon for certain routes to increase in latency during the day and return to normal later.
If you've chosen to query the authoritative nameserver for DNS, that would also be slower than using default DNS server for the location.
If just the SSL handshake time increases, it could indicate high load on the offloader / server, assuming that it still accepts socket connections in a timely manner.
