    HI i need to finetune my scrapingproject. we have a 3 provider proxysetup that continously looks (3x times per second) if new ads are available, and if so get the phonenr from api of that ad sent to a phonesystem. Now we have the ad timestamp available on site, and at the end the timestamp at our server when we get the ad. There is our problem, this time differs between 0.5 - 7 seconds. Our datafetching time is less then a 0.6seconds. I dont understand if we look 3 times a second with proxy, and fetchtime 0.5, we should be able to get the phonenr within one second. Any one has a solution for this.

    Hi I have an ongoing problem from few hours. My server appears to be performing a portscan toward 'random' ip addresses and udp ports. The process that is sending those packets is Asterisk which was already at version 16.29 and I've upgraded it to the last version, 16.30 but the problem persists. I can't provide ssh access to the server but I can provide whatever packets captures you prefer. I'd like to know the source of the problem, if it's some virus in the office of the client or some external attack. Max 100 euros.
