[From an email I sent out on Monday, May 14th, 2012:]
I noticed last week that the feed from the LLBP7 station had been interrupted again. Last week I was hugely busy, however, and by the time I sat down on Friday to send out an alert email like this one, the data feed was working again. I think it was probably offline for about two or three days.
[From a reply by Ross Timmerman, later that same day:]
Last week the modem was offline a few days and I reported it to Docomo. They responded fairly quick asking me to try connecting again, and it was fixed. I asked Docomo what did but they never elaborated, nor did they explain why the outage occurred. I will keep an eye out for connection issues and keep Docomo posted.
