[AusNOG] High Latency to AS15169

[Dave Browning]

Hi Jen,

Looks like your front line aren’t aware of the issues, see response below;

Hi,
 
Google does not recommend using ping time to google.com [or any other Google service, including Google Public DNS, or 8.8.8.8] as a measure of the actual performance of Google services for the following reasons:
 
- Google services, including Google Public DNS, are not designed as ICMP network testing services
- Many large networks, including Google, rate limit ICMP
- ICMP ping or traceroute traffic can be discarded or delayed en-route to Google
- The termination point of the TCP/UDP session with Google may not represent the full network path between a user and the service
- User requests may be served from locations closer to or farther from the user than the destination of the initial TCP termination point
- Even a complete lack of response to ICMP traffic may not reflect any sort of issue with Google service performance.
 
Please do let us know if you actually getting complaints from your users about accessing Google services.
 
FYI, you may also want to read this about icmp and traceroutes to Google

Just to let everyone know - the problem is being investigated right now.

All,

I am seeing high latency into Google's network from both our network and also my home network. Is everyone else seeing this? Examples are 8.8.8.8 and 35.185.160.2
We direct peer with them. Looks as if my home ISP do too.

Latency seems to jump at the same spot from both networks, between 108.170.247.75 and 216.239.35.142 (both Google IPs).
Have sent NOC a message, but just be interested to see if others are affected.
