What is the reason for these outages? Today the forum was 
multiple times not available for minutes. I got no repsonse, 503, 
451, the message mentioned by Brian, and also Proxy Errors.

Is this a hardware, a software, or a bandwidth issue?

Kind regards,
Stefan

For me it happened almost every day last week and today. And 
sometimes the page is very very slow to load (About 20 seconds).

I wouldn't mind to help financially in this case, but then D team 
needs to tell us how to do it.

 Hm... (n%3+3)%3 should work.

If the divisor is negative you can just add dividend after the 
modulus and get the same result like Python. In this way you save 
one % operation.

Sorry about that.

I've been trying to find a more permanent solution to the 
performance problems plaguing the forum (and other D services 
hosted on the same server), and trying several things to make it 
work with the current hardware. Unfortunately, it's a slow-going 
process, and causes further performance issues while it's running.

As of a few days ago, the forum's database is now on a dedicated 
partition. (Even though it's on the same physical disk, the 
dedicated partition allows bypassing the sync queue from the rest 
of the system.)

Performance should now be much be much better, and according to 
my observations, it has improved.

What is your experience?

Just this morning I clicked on a link in a post (use Thunderbird 
normally, so I'm not a regular user of the forum), and it was "down for 
maintenance" 2x, then finally came up.

Would you happen to have a more exact time?

Here are the holes in today's log (UTC):

2019-01-25 07:02:49 - 2 minutes, 30 secs - daily backup
2019-01-25 14:53:54 - 4 minutes, 42 secs - unusual lag spike
2019-01-25 15:02:36 - 1 minute, 38 secs - unusual lag spike

I still need to figure out those lag spikes (single requests / 
database queries that take much, much longer than they should), 
but knowing if it's one of those would allow me to know if the 
problem you saw was there or elsewhere (such as the reverse 
proxy).

Proxy Error

The proxy server received an invalid response from an upstream

The proxy server could not handle the request GET

Just as I entered this thread to read the two new messages :)
