Hey Remitur & Paul,

thanks for addressing, but no idea how this could get improved. The solution is basically to disable the registrar module in such a case.

We cannot introduce a http request timeout as some api requests may take minutes to complete (3 minutes is our timeout for backend system requests). if our API isn't available, we immediately return with an error message. But as long the api is accepting connections, but is not able to respond as of an ongoing ddos attack, not sure how that could be covered.

Paul is at least right that disabling widgets that are communicating with our api, is worth it to get at least the whmcs admin area accessible.

@papakai I just realized you're under DDOS (the message was about some kind of "scheduled maintenance") I am sympathetic to you (DDOS authors need to die. Slowly and painfully.)

BTW: your collegues in a communication wrote

Since one of the counter measures is to use an additional IP filtering we would like to provide us with your connecting IP address for whitelisting purposes to make API access available again for you.

But not specified HOW to provide the IP...

[KaiSchwarz-cnic]

yes, I guess they noticed that issue already - things that happen in urgency. mail the ip address(es) to "help at hexonet dot support"

Hi Kai,

One of the last emails mentioned this:

Since one of the counter measures is to use an additional IP filtering we would like to provide us with your connecting IP address for whitelisting purposes to make API access available again for you.

Please let us know if you have any questions.

Where can we do this?

I cannot see anywhere to do this?

Thanks

I am curious where ***@***.*** goes to.

Again for clarification (further people checking this thread):

mail your WHMCS System's >>outgoing<< ip address(es) to "help at hexonet dot support"

[KaiSchwarz-cnic]

fyi, I've been revamping our widgets to be more performant and reliable. Caching data in Session, possibility for deactivation. Just the domain monitoring widget can't benefit of a caching mechanism otherwise we eventually deal with false positives/wrong data in the analysis part. Suggestion: Use the new icon to keep that widget turned off in general and turn it on once a quarter or so to see if everything is fine and then turn it off again after.
