• Chad: We do not have a target in Chad.
• Benin: Looking at http://www.slac.stanford.edu/cgi-bin/pingtable.pl?file=average_rtt&by=by-node&size=100&tick=last365days&from=EDU.SLAC.STANFORD.PINGER&to=Africa&ex=none&only=all&ipv=all&dataset=hep&percentage=any Benin  Benin in the last 365 days had both its targets unreachable Aug 6-7, 2019, however that does not match what was reported (see https://www.voanews.com/africa/benin-internet-shutdown-repeats-pattern-government-censorship-across-africa, which was posted April 30th also see https://netblocks.org/reports/internet-blocked-in-benin-on-election-day-aAwqkny) which indicates the outage was April  28th starting at 11:00 am UTC). Note the Benin outage lasted 15 hours so it was not down for a whole day, thus we would miss it using the daily data. It would be necessary to mine the hourly data.  Looking at http://www.slac.stanford.edu/cgi-bin/pingtable.pl?file=average_rtt&by=by-node&size=100&tick=hourly&year=2019&month=04&day=28&from=EDU.SLAC.STANFORD.PINGER&to=Africa&ex=none&only=all&ipv=all&dataset=hep&percentage=any however, I do not see either host in Benin being unreachable (100% loss) on April 28, 2019. Maybe there is a proxy elsewhere which was not affected, although the  RTTs look reasonable. 
  Looking at  the raw data, we get no response starting between 11:30am and noon and ending between 23:00 and 23:30 UTC April 28th UTC for www.uac.bj(lat=6.4410 , long=2.3527 at Universite dAbomey-Calavi, Abomey Calavi, Benin) and also for www.officedubacbenin.bj(lat=6.35, long=2.433 at Office Du Bac, Benin, Cotenu, Benin)
• Democratic Republic of the Congo: Looking at the analyzed data, the DRC (CD) does not appear to have any all day outages for either of the two sites monitored in Kinshasa (www.afrinet.cd and www.gbs.cd). There is a report of outages in the capital of Kinshasa (see https://www.bbc.com/news/world-africa-46721168) the Internet in Kinshasa was shut down in the morning (the report is for Dec 31st, 2018). I looked at the hourly data for the 2 Kinshasa node and do not see any outages for Dec 30, 31 and Jan 1st.
  Looking at the raw data www.afrinet.cd does have an outage (see https://www.slac.stanford.edu/cgi-wrap/ping_data_plot.pl?monitor=pinger.slac.stanford.edu&sites=www.afrinet.cd&begin_day=26&begin_month=12&begin_year=2018&end_day=31&end_month=12&end_year=2018&plot=time&data=100&full=false&bin_width=1&data=100&debug=1). There was no response after 10:47 am 12/31/2019, and the next recorded response was 18:17 12/31/2019 (UTC).  The other node www.gbs.cd does not see any loss of connectivity.
• Sudan: Looking at https://www.npr.org/2019/06/16/733158506/sudans-internet-outage?ft=nprml&f=1004 they report on June 16th, 2019 that the entire Sudanese network has been down for the last 13 days. Also, see https://netblocks.org/reports/severe-internet-outage-across-sudan-amid-reports-of-darfur-paramilitary-attacks-aAwq0oyM that reports that 70% of Sudan's Internet has been blocked. There are two PingER targets in Sudan but only one (www.sustech.edu) has worked for a long time (I will try and find another target and replace the nonworker) and the working one has not seen an all day outage in the last 365 days.
  Looking at the raw data (see https://www.slac.stanford.edu/cgi-wrap/ping_data_plot.pl?monitor=pinger.slac.stanford.edu&sites=www.sustech.edu&begin_day=01&begin_month=06&begin_year=2019&end_day=21&end_month=06&end_year=2019&plot=time&data=100&full=false&bin_width=1&debug=1) there is no noticeable loss of connectivity (loss=100%) between June 1st and June 21, 2019 UTC.
