Title: Slow server - DOS attack
Post by: grahame on August 23, 2021, 12:17:46
Ladies and gents, you may have seen a degraded service over the past hour ... some tw*t has decided (or more likely accidentally or in the side effects of something else) decided to run a denial of service attack again our server ... I like enthusiasts for the site, but 32 requests per second (intricate searches) is a bit OTT ...

I have forbidden the visitor ... still knocking at the door but being told "go away" at triage rather than getting through to the main enquiry desk and specialist search service!

Greetings from off the Mull of Galloway!

I was going to say "There's always one" - but sadly it is many times that many.  A total pain.

I am currently struggling with someone who insists on filling one of my contact forms with incomprehensible Russian characters.   I have no idea what they intend to achieve.  If it is to wind me up, they are succeeding.  If they are trying to sell something I have no idea what it is - but I can probably guess.  Either way it is now getting autodeleted.

I thought you had taken the server with you and were running it off your cabin WiFi   ;D

Old thread ... sorry if you have found our server a bit slow this afternoon - we have had a Denial of Service attack.   It didn't end up denying service mind you, just slowed us down a bit. I'm watching / ongoing in case I have not managed to fully fix the thing.

Database image search requests up from 111 on Tuesday to 131,050 on Wednesday at a peak rate of about 16 per second. All quiet this morning - 32 requests so far to that page out of around 16,000 requests to our server.
