Just a heads up, ourselves and many other ISPs both in NZ and internationally have started seeing a couple of DrayTek CVE's being exploited over the last ~24 hours.

One of the symptoms of this is the internet connection bouncing up and down, due to the DrayTek encountering a buffer overflow from these exploits.

While I don't have all the detail, general rules apple:
If you're using a DrayTek router, please ensure it's up to date.
If you're using a DrayTek router and your connection is bouncing up and down hinting at being hit by the exploit, reset it, update it, and reconfigure.
