[outages] Interoute issue in London

[Chris Taylor]

Interoute are having a major issue in London - we're seeing it affect 
several circuits from them.

I believe they have multiple master tickets open (one for each team), 
but one is 1-500518083.

An engineer should have arrived on site approximately an hour ago.
Their call centre is *very* busy - been in a queue for about 25 minutes 
now trying to get an update.
