Site performance, Server errors, outages and tunings

The VPS was down for 1 hour again. But now I think I understand what's going on.

At 12:01 all VPS'es (except mine) begin to process 24-hour logs thus overloading the disk.

A ticket has been logged. Waiting for a response.

BTW, they replaced a disk on Saturday.

nice

Yep, love it. I have several rules for simultaneous connections per IP, per site directory and total requests per IP within 10min. All rules work - seen in the logs.

I'm beginning to get more fun from tweaking, than from the actual content 😁

Have you switched of the code 'validation' for comments against your Blog?

....or is this another feature designed to challange your mighty bug fixing talent?

😁

Yeah, removed the captcha for several reasons.

o- if you enter a wrong code, you will lose you comment and have to type from scratch, what is very frustrating
o- additional code to load
o- it creates a session file with a code on disk and I would like to reduce disk operations as much as possible
o- Internet community finds captchas annoying, many people simply refuse to leave comments
o- captcha does not prevent SPAM completely. I was getting ~10-15 SPAM a day with captcha (~50-70 without)

Finally I've got some attention from the provider! They are going to change the other VPSes' crontabs to distribute the load. Yeeeehhaaaa!!!! Took me 8 months to convince them.

Something happened with DNS today. The likera.com was not resolvable. Had to restart named several times.

Never seen that before. It was not working since 5 hours ago. Nice ...

Looks like another bug in either kernel or named. Had to explicitly set the maximum open files limit. Weird ...
