Odido: Internet hangt (half)

Gewijzigd naar 8.8.8.8. 

DNS lookup vertraagt nu ook nog van tijd tot tijd. Aantal keren achter elkaar:

dns.sh

# start_ms=$(ruby -e 'puts (Time.now.to_f * 1000).to_i')

# do some work

# nslookup mensura.g.aaplimg.com

# end_ms=$(ruby -e 'puts (Time.now.to_f * 1000).to_i')

# elapsed_ms=$((end_ms - start_ms))

# echo "$elapsed_ms ms passed"

#

Output van verschillende runs achter elkaar (zie laatste van 5 seconde, en dit is herhaalbaar):

DNS teruggezet naar default… Trage dns is nu niet meer reproduceerbaar.

En het is weer terug…. Nu ook terug te zien in networkQuality output
