2026-02-12 downtime

The ISFDB Web site came under a concentrated bot attack on Thursday, February 12, 2026 around 6am server (EST) time. We began deploying countermeasures in the afternoon. It may take another 24 hours or so for the new settings to be set up and propagated across the internet. Sorry about the interruption!

 

2026-02-13 9:05am EST update: The countermeasures have been deployed and the site is back up. 

2025-08-26 - Unscheduled downtime

3pm:

 

The ISFDB server is experiencing difficulties due to very high loads. Some Web pages may not load properly. There is no ETA at this time.

3:12pm:

Performance should be back to normal. 

2025-06-17 - Workaround for network connectivity problems

If you are running into timeout and "server not found" errors while trying to access the ISFDB server, the following steps should be able to help if you are running Windows:

1. Press and hold the Windows key + R to open the "Run" dialog box
2. Type ipconfig /flushdns into the text field and click OK

This command tells your PC's Windows to get the latest internet address for the ISFDB server, which should fix the immediate problem. Whatever issues the ISFDB server is currently experiencing may still result in occasional "timeout" and "server not found" errors, but they seem to be relatively rare. All you have to do is reload the displayed page (press F5) to get past them.

 

It's possible that the hosting company may change its configuration settings yet again, in which case you will need to re-do the steps listed above, but we'll cross that bridge when we get to it.

2025-03-24 edit: Disabling anonymous access to the ISFDB Wiki seems to have stopped the bad bots, at least for now. We will continue monitoring the situation.
