    Egypt - Citynethost

    Our services at Citynethost in Cairo went down a little over 3 hours ago. Their web site is also unreachable.

    http://www.downforeveryoneorjustme.com/citynethost.com

    I'm not sure if this is specific to them, or if the government has decided to cut the Internet ahead of Friday prayers again.

    Has anyone any info please?

    EDIT: Looks like their IPs aren't being announced again, so it's possibly political rather than technical

    I can't see any IP blocks being announced from CityNetHost's AS33785 in any of our BGP feeds, but there are plenty of announcements out of other Egyption ISPs, including AS24863 (LINKdotNET) who seem to be the single upstream transit provider for CityNetHost.

    Looks like the BGP withdrawls happened about 07:40 UTC.

    Thanks for that. Still not sure if it's political, or someone forgot to put a quid in the meter

    Glad to hear you're back up and running lets hope that it stays that way!

    It looks like the BGP re-announcements started about 11:50 UTC.

    I cut them a lot of slack at the moment following all the unrest and government interventions in Internet, mobile networks etc. They provide great service when they're up, so I hope no-one reads too much into this thread... I'm certainly not blaming them for this outage until I hear different

    Yep! I can reach them from the UK, Germany and various USA points. Where are you located? The BGP announcements may not have reached your part of the world yet.

    From the brief investigation work I've done today, CityNetHost has a single upstream transit provider - LINKdotNET, who in turn have two upstream transit providers - Level3 and GlobalCrossing. You appear to be getting to the point where Level3 hand off to LINKdotNET in Paris, but then it appears that you are not making any progress on LINKdotNET's network.

    The BGP re-announcements have reached you, hence why you can traceroute to the IP address without dying inside your own ISP's core network.

    If you want to PM me the IP address that you are tracing to, I can compare your results to my own from our network in the UK and see what you should be expecting to see after hop 15.

    Ultimately though, you are going to need to open a ticket with CityNetHost so that they can work with LINKdotNET to troubleshoot the underlying problem for you.

    I can currently see announcements for 41.215.240.0/22, 41.223.52.0/22 and 196.46.188.0/22 coming out of AS33785 and can ping/traceroute to 196.46.189.254 from our network in the UK, which then goes via GlobalCrossing.

    Yup, looks to be the same problem again - lots of BGP withdrawals about 15:12 UTC eventually leaving AS33785 completely isolated

    We lost them about 50 minutes ago but they're back now. Lots of latency and packet loss at first but looking more normal now.

    Yeah, 15:12 UTC was about an hour ago, so that fits time wise. Looks like BGP re-announcements happened at about 15:48 UTC

    Only CityNetHost will be able to tell you the exact reason for the problems that they have been experiencing, but they are single homed onto LINKdotNET, which means that they rely on a single internet service provider and thus there is an easily identifiable single point of failure.
