For the past two days, we have seen several reports of intermittent Error 400 and Error 500 problems when workflow rules attempt to create PDF attachment files. I reported this problem to PDF Rocket support. PDF Rocket is the web service we use to create PDF attachment files.
I just got a response from PDF Rocket support.
They have had an intermittent outage which was causing these Error 400 and Error 500 problems.
They have now corrected these problems.
Here is the text of the response they sent me describing why the problem occurred and what they are doing to avoid such problems in the future.

"Thanks for your patience. Full service has been restored. We apologize for any inconvenienced caused. Furthermore, we have restored 3 weeks’ worth of credit back into your account.
We’ve had an outage that caused 1 in 5 requests to fail. This seems to have been caused by excessive disk space utilization. At the same time, our support staff had issues accessing the support mailbox.
We are making the following changes to ensure this doesn’t happen again:
Doubling our server fleet size.
- Increasing processing power on servers by a factor of 4 (i.e. resulting in a total 8-fold increase in PDF conversion capability).
- Improving granularity of our monitoring.
- Re-imaging our servers on a weekly basis as a workaround until we can find the root cause of the excessive disk space utilization.
In addition, we will be moving from email based support to a better support desk system (with announcements, automated assistance and better keeping customers informed an up to date)."
