Page Type: SYMPTOM
UPLOAD CONNECTIVITY ERROR means that for the past several hours or more, all or most transmissions could not be directed into Rangecast because upload of audio to Amazon's cloud service failed to complete.
UPLOAD CONNECTIVITY ERROR means that for the past several hours or more, all or most transmissions failed to upload to Amazon's cloud service. To report an "Upload Connectivity Error" the feed site software must be in communication with Rangecast's servers, so this message does not indicate that the feed site is currently disconnected from the internet (although this message may occur immediately after an extended internet outage, once the site is working again, reporting the recent unreliability of the connection to Amazon.) The inability to upload audio to Amazon's servers indicates a significant problem with internet connectivity.
PATTERNS THAT MIGHT HELP IDENTIFY A CAUSE - We have observed the following patterns:
* CAUSE MAY BE OUTSIDE THE LOCAL NETWORK - It is not uncommon for multiple PCs at different geographic locations, all within the same corporate LAN, to show the symptom simultaneously. This suggests that the failure mode can occur due to a network problem that is upstream from the feed site PC. On rare occasions, we have seen this error message from feed sites operated by different customers who are in the same wide geographic region (e.g. adjacent states), or using the same Internet service provider. Therefore, we suspect that the cause may sometimes relate to network performance far upstream from the customer's own equipment, in the ISP or internet backbone route between the customer and Amazon S3.
* PROBLEM USUALLY RESOLVES WITHOUT ATTENTION - In the majority of cases, the symptom appears for about 3 to 24 hours, and then vanishes without any evident cause without manual intervention or maintenance, and no known factor correlated to the timing of the incident.
* SPEED TESTS MAY BE NORMAL DURING DISRUPTION - An affected PC usually shows good performance in general internet "speed tests" (bandwidth, latency, etc.) The cause of the problem may relate to some specific fragility that is not revealed in consumer-oriented tests of general internet performance. For example, the cause may relate to fragility along the network route to Amazon S3, or a quality that is relevant to the upload/retry/timeout process involved in file uploads.
* LOCAL NETWORK OVERLOADING IS A POSSIBLE CAUSE - In the few incidents where a cause has been identified, the issue was high-bandwidth network usage, such as video streaming or video production, on the same LAN (either with the Internet, or locally between devices.) Reducing other loads on the LAN improved performance. However, usually no cause was ever identified, so this is in the "something to try" category, not an expected fix.
THINGS TO CHECK:
(1) IS PC CLOCK SET CORRECTLY? - If a Clock Error (Code 31) alarm is also present, the PC clock is not set to the correct time or time zone, and this may interfere with security protocols required by Amazon for data transfer.
[FAQ-1053] Error Message: CLOCK ERROR (Code 31)
The CLOCK ERROR message warns that the PC clock is wrong and not synchronized with the Rangecast server. A RED BOX warning with "CLOCK ERROR" displays on the Sender during this condition. If the clock is off by more than 15 minutes (or set to the wrong time zone), this prevents the Sender from feeding audio. This is a disabling problem but is easily fixed. NOTE: this FAQ relates only to a clock error displayed on a PC recording audio, and is NOT related to clock error messages on a PC playing audio.
