 ## burble.dn42 Maintenance Log
 
+#### 10th May 2019
+
+dn42-us-chi2 was suspended by the provider on 8/5 due to 'NTP reflection attacks'.
+
+This is a hazard of running a busy NTP server as part of the (NTP Pool)[https://www.ntppool.org/en/);
+providers can get twitchy when they see a large amount of NTP traffic, due to the well publicised
+vulnerabilities in stock NTPd.
+
+My network uses chronyd rather than NTPd and it is simply not vulnerable to abuse in the same way
+as NTPd, I also regularly monitor and check the services. On the other hand, the server does see
+a large amount of NTP traffic and it can sometimes be difficult demonstrating that I'm
+specifically providing a service here and not under some kind of attack.
+
+Apologies that the server was offline for a few days, but it should now finally be back again. 
+
+For info, here is the bandwidth graph of dn42-us-chi2 as it was suspended:

+
+It's trivial to see that an amplification attack was not occuring, as the inbound and outbound
+traffic are both equal. It's a shame some providers don't consider this before suspending services,
+but, understandable that the economics of providing VPS services can prohibt this.
