Hey All,
I’m on Hyperoptic yesterday evening I noticed some of my home devices were out
of sync with reference time - a quick test with ntpdate showed time.google.com
<http://time.google.com> , time.cloudflare.com <http://time.cloudflare.com>
and time.apple.com <http://time.apple.com> were timing out over IPv6 (across
all the IPs of their round robin).
mtr towards these endpoints, poirt 123 fails just after my home router (their
standard Hyperhub, nothing custom):
❯ mtr time.google.com --udp -P 123 -bzw

Same endpoints, port 124 go through without issues
❯ mtr time.google.com --udp -P 124 -bzw

I’ve found this
https://www.reddit.com/r/hyperoptic/comments/gj9jaz/issue_with_ntp_over_ipv6/
<https://www.reddit.com/r/hyperoptic/comments/gj9jaz/issue_with_ntp_over_ipv6/>
where people has been reporting the same issue since three years and also
tried contacting their customer service but despite me having provided detailed
info and troubleshooting they are saying they can only go through their
standard troubleshooting runbook and not escalate / review (what a response!).
Is anyone else seeing the same happening as we speak? The direct test would be
"sntp -S time.google.com <http://time.google.com> ” on MacOS or "ntpdate -d
time.cloudflare.com <http://time.cloudflare.com> ” on most unix.
Additionally, is there any good soul from Hyperoptic/AS56478 who can look into
this? This kind of issue is particularly impactful to non-technical users as
it’s hard to troubleshoot and leads to 2FA (banks, etc) failures due to time
being off sync. If it’s a widespread problem (which the Reddit threads makes me
think it is), customers will greatly benefit of a solution.
Thanks!
G
