ThinkGrid Advisory - Peering Issues.

Advisory - Peering Issues

The following advisory discusses an ongoing incident.

We have received reports o dropped packets and high latency to connections across multiple routes from and to multiple hosts spread over a geographically disperse area in the United Kingdom, which we believe is related to a peering issue at the London INternet eXchange (LINX). We are currently monitoring the situation and will update our customers as the situation evolves. This will result in loss of packets and poor connectivity but will not permanently affect any data or infrastructure belonging to ThinkGrid.

UPDATE 16:58:28 - We now believe this is stabilised although we will continue to monitor the situation.

Date and Time:

 2012-05-31 16:29:53 Ongoing

System(s) Affected:

Connectivity to multiple data centres

Scope:

Multiple services

Impact:

Loss of packets and poor connectivity

Important Announcements - Using the Service Desk
Posted by Matt Platts on 09 May 2012 12:54 AM

News Subscriptions - Planned Maintenance

As you may have seen from recent news articles, ThinkGrid is adopting a standard format for planned maintenance notifications. Where planned maintenance does not entail specific precautions for certain customers and does not demand a specific or confidential distibution list, we will notify on our Service Desk site, through the News function. You may receive news articles by Subscribing to the ThinkGrid Service Desk, which you can do from the front page using the Subscribe link. I strongly recommend any interested parties take part.

On a secondary note I'm pleased to note that we have introduced a new short article on how to use the ThinkGrid Service Desk website as effectively as possible - this guide is well worth consulting as it outlines some of the many useful features of the site - including reviewing status of tickets, using 'widgets' to accomplish certain tasks quickly and effectively, and rating agent performance in individual tickets to aid in ThinkGrid service improvement. You can find out more here.
