Hi,
At approximately 00:45Z this morning, customers with DNS domains
hosted by BitFolk would have started receiving lots of CRITICAL and
then RECOVERY alerts which went on through the night. Also,
customers who monitor external DNS servers with their own software
may have seen similar issues.
This was due to rate-limiting of UDP/53 traffic put in place by our
transit provider without our prior knowledge. I have been in
discussion with them and the change was backed out at around 08:20Z.
There is no need for you to take any action.
We are still investigating the full extent of what took place. If
you have any evidence that DNS queries (other than those from your
monitoring software) failed, I would be interested to know. Please
do let me know off-list.
Now that the rate-limiting is disabled I do not expect further
problems but I will follow up on what happened when I have more
information.
Cheers,
Andy
