E2E Networks
We are observing and also reported network reachability issue in our Delhi(NCR) region zone. We are investigating it currently and will keep you posted on further findings.
Update - 14:00 IST, 16 March 2022
We had network disruptions for multiple durations (15 mins avg multiple times ) on 14th and one degradation on 15th for about 10 mins. We have investigated this extensively and have a preliminary analysis of the events and the mitigation being done and steps being taken to ensure the issues don't recur.
We had a differentiated DDoS (Distributed Denial of Service) Attacks and the variation was of targets also being highly distributed across our entire network. We have mitigated this novel DDoS by using blockhole filters to negate the traffic inflow. The network is currently stable for the last 16 hours and we are closely watching this.
The network is stable now and no reachability or drops are being observed now. We are keeping a close watch over it and we'll keep on posted with further updates.
This is to inform you about a scheduled upgrade activity on our core network switches.
Maintenance Date and window: 8th March 2022 from 01:00 hrs to 05:30 hrs IST
Downtime: 5 minutes of network downtime
Impact: All the resources and services in Noida(NCR) Location will be facing network downtime for 5 min or less. In case of any unexpected challenges while performing the activity will extend the activity up to 10 min to revert back all the changes. All the resources and services will be up and running post the downtime period.
Few important impact points related to this maintenance activity
Myaccount Portal: Our E2E Myaccount portal will not be accessible during the downtime.
Compute nodes: There will be a disconnect of the network (both public and private) for a period of 5 minutes or less for all the compute nodes in the Noida (NCR) location.
Volumes (or BlockStorage): There will be a disconnect between the BlockStorage volumes and the nodes they are attached to which may cause I/O error while the volume is being accessed. We recommend verifying the accessibility of the BlockStorage volumes from the concerned node and trying unmounting and mounting the volume again if you face any issue in accessing it post activity. In case unmounting and mounting doesn’t make it accessible, try detaching and attaching the volume again post activity to get it functional again. Please refer here to know more about detaching and attaching BlockStorage volumes. We recommend you unmount the BlockStorage volumes before the activity and remount them once the activity is completed to avoid the aforementioned issues.
Object Storage: The buckets and objects will not be accessible during the downtime period.
We request you to take the above maintenance into consideration & plan your activities accordingly.
Note: If you have a cluster-based setup on your compute nodes, due to this network interruption between nodes, there could be a break in the cluster. We suggest you set it on a standalone mode so that you can resume sync between them post the activity is completed.
For example, if you have a PCS based cluster, DRBD cluster, Mongo Cluster, or any clusters, etc.
We regret the inconvenience caused to you in this regard & look forward to receiving your continued support. If you have any queries, please reach out to us at cloud-platform@e2enetworks.com
This is to inform you that we have scheduled an upgrade activity for our backend software stack version for E2E Networks Object Storage on the 3rd of March 2022 between 8 PM - 10 PM in our Delhi/NCR.
During the maintenance activity, all operations on E2E Networks Object storage from the MyAccount portal will be affected. However, the direct operations using the SDKs and clients for E2E Networks Object storage will continue to function normally.
Upgrade activity has been completed successfully last night(3rd of March 2022) for E2E Networks Object Storage. With the newer software stack, the dashboard/console available at the direct browsing of the URL https://objectstore.e2enetworks.net/ won't be available anymore.
All the UI-based operations are available via the MyAccount portal only. All the command line or API-based clients or SDKs won't be affected and their usage and operations will keep on working as expected.
This is to inform you that there is a scheduled upgrade activity going on for our backend software stack version for MyAccount Dashboard on the 1st of March 2022 between 8:15 PM - 8:45 PM.
During the maintenance activity, the access to MyAccount Dashboard will be affected. However, all the resources will work without any issues.
We will update you as soon as
Issue in accessing the virtual machines in Delhi(NCR) region over the network has been observed and reported from a few of the ISPs like Vodafone, Railwire, Jio, etc. though reachability works from airtel networks. We are investigating it currently and will keep you posted on further findings.
From different online and offline sources, we have been informed that all Airtel connections ranging from fiber internet, broadband, to even mobile network is down in regions like Delhi, Mumbai, Noida and many other locations. Outage tracker https://downdetector.in/status/airtel/ shows Airtel internet having problems since about 11:30 AM on Friday, February 11.
You can reach out to us at support@e2enetworks.com and report if you face such connectivity issues.
No past incidents to show.
