Can we relate access blocking of service to the service availability? for example, can we say google search engine has limited availability because it’s blocked in China?
I’ve been trying to buy Super Fastpass from www.booktickets.disneylandparis.com but the whole of September is greyed out (“not eligible”). Does that mean those Fastpass tickets are not available in autumn/winter or that they’ll probably become available later?
So, I've been with a lot of hosts in last 6 years. Currently I'm with Cloudways with a DO droplet.
The only problem is that the people near to my datacenter have good load times due to low TTFB. But on the other places away from my datacenter, TTFB is pretty high which makes the load time miserable.
Now, I know CDN should help here to make the site contents load from their nearest server. But the issue is that CDN only caches the static contents of a site like CSS, JS, and images. While…

I have just installed a sql server availability group,
always on, with 2 servers,
SQLPROD2_TS as you can see on the picture below:
select distinct rcs.database_name, ar.replica_server_name, drs.synchronization_state_desc, drs.synchronization_health_desc, CASE rcs.is_failover_ready WHEN 0 THEN 'Data Loss' WHEN 1 THEN 'No Data Loss' ELSE '' END as FailoverReady from sys.dm_hadr_database_replica_states drs inner join sys.availability_replicas ar on drs.replica_id = ar.replica_id and drs.group_id = ar.group_id inner join sys.dm_hadr_database_replica_cluster_states rcs on drs.replica_id = rcs.replica_id order by replica_server_name
the listener for the availability group is calle
SQLPROD_TS as you can see on the picture below
select * from sys.availability_group_listener_ip_addresses select * from sys.availability_group_listeners select * from sys.dm_tcp_listener_states
all is good, however, when I ask people to connect to
SQLPROD_TS when they browse the network they can only see the nodes of the cluster.
Is there a way I could make
sqlProd_ts to show up on the picture above, instead of the nodes?
I do not want to use my mobile phone (hoping it is not that necessary) in UK.
Where do I get to use public telephones in UK and at what prices?
If I want to implement both AlwaysOn Availability Groups and Encrypted Channels, how would I do this?
There is a desktop application (Visual Studio 2008 built) that interacts with this database, and the client wants traffic between the application and the database encrypted. They also want redundancy in the database.
I’m new to this thus I’m trying to understand about calculating Disk Array Availability (DAA).
What I have understood so far is that availability is always 1, and Failure = 1÷MTBF, and that is all I could understand since morning.
Assume I have 1TB and the time is 5 years, and the disk’s MTBF is 1.6 millions hours (got this from Dell’s website for a 15K RPM disk), I need to know the availability of this disk in 5 years, how do I calculate, what is the formula, I’m seeing MTTR, and MTTDL and some other MTTs and getting confused.
Another confusion is, is disk array availability associated only with RAID.
Could someone explain in simple English how to calculate DAA.
Appreciate the assistance.
Currently I’m using this as reference : http://www.ecs.umass.edu/ece/koren/architecture/Raid/reliability.html (this reference has only formula with minimal or no explanation)
If anyone knows of any other good reference that explains in simple English.
