I am receiving errors on our website when customer tries to purchase a product. We believe this is an issue related to a HTTPS canonicalization issue. Our previous server expert solved this same exact issue on year ago. These were his notes: "your server has CentOS 5.9 installed, so it doesn't support SNI, so there was a subdomain mess. I've just had to make some changes to webserver configuration so solve the issue" We are seeking professionals with server-side development experience who can help us with this issue. We also have some future ongoing back-end and front-end work in the future that we can give to you if you can help us out.

Firstly, We have couple of sites setup on a dedicated server, over the last few weeks we have been having problems where the sites have stopped responding for short or long period of times, some of the errors we would get are Service Unavailable - The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later. Additionally, a 500 Internal Server Error was encountered while trying to use an ErrorDocument to handle the request. 502 Bad Gateway Nginx Internal server error – The server encountered an internal server error or misconfiguration additionally a 503 service unavailable error was encountered We either restart the server and issues are resolved or sometimes even after restarting server and or services such as nginx and apache the problem continues Then the site run absolutely fine and fast loading – it is an intermittent issues so it can happen anytime but seems to be happening more over the last couple of weeks and now on daily basis maybe even several times throughout the day randomly. We need a specialist to check all our server settings and log files and fix these issues and prevent them from happening in the future, optimise the server so all of its resources are being utilised ensuring fast and error free server. 2. We need to check and resolve why aws stats are not working on our site 3. setup 2 domains we want to run on the server – make them run with the server software such as nginx apache and server cache etc to make sure they are setup fast and using all of the servers software.

Looking for a high-volume auto dialer that is capable of dialing over 1,000,000 phone numbers per day. When people press 1 to confirm their interest, the system will need to Dial a partner's phone # (DID) and blind transfer right away with the caller ID (blindxfer, unless other method is recommended). Speed is critical and the system will likely need to be a pure-Asterisk system with no extra fluff, and a custom dial plan. System needs to be able to handle 300-500+ outbound channels at once with large rate of playback (and hopefully outbound transfers as users press 1 to confirm). Ideally we want to dial out 1-5mil numbers per day and transfer/connect 1-10k press-1's to agents, reliably at-will. If this sounds like something you might've already built in the past or have lots of experience with, please apply for this job. Need a basic solution in place by tomorrow morning if possible, with further refinements over the weekend.
