I want to jump into this topic too, but before a Happy New Year to everybody.
Was wondering too, for December my probe got an total availability of only 98.17% - and which is in fact not true. I'm on a VDSL line 50 mbit from German Telekom, and every night my router has to re-establish the connection to get a new public IP. According to the log files from my router this whole process takes only a couple of seconds, but in the Monthly probe report from atlas the time between Disconnected and new Connected is around 20 to 30 minutes, see examples below:
+---------------------+---------------------+------------+--------------+ | Connected (UTC) | Disconnected (UTC) | Connected | Disconnected | |---------------------+---------------------+------------+--------------+ | 2015-12-26 02:35:51 | 2015-12-27 02:06:06 | 0d 23:30 | 0d 00:27 | | 2015-12-27 02:31:20 | 2015-12-28 02:04:36 | 0d 23:33 | 0d 00:25 | | 2015-12-28 02:39:09 | 2015-12-29 02:04:29 | 0d 23:25 | 0d 00:34 | | 2015-12-29 02:31:40 | 2015-12-30 02:03:09 | 0d 23:31 | 0d 00:27 |
Hi, I'm not completely sure, but I think the problem is that the probe is waiting for a TCP connection timeout. I guess that for some reason the probe doesn't get a TCP RST. Might be a firewall problem somewhere. Philip
